User Manual dolphicam2

Version 1.3.1

Congratulation and thank you for getting the dolphicam2! This document is the user manual for the dolphicam2 ultrasound camera platform. The dolphicam2 ultrasound NDT platform consists of a black box (BB) and a wide range of Transducer Modules (TRM) with different frequencies and coupling materials. dolphicam2 is delivered integrated with a Panasonic Toughpad FZ-G1 where the black box is attached to Toughpad by an x-frame.
We appreciate your feedback on the user manual, so you find that you are missing any information, or anything is unclear in the user manual, please contact dolphitech support.

Transducer Technology

The dolphicam2 platform has a transducer with 128 transmitting electrodes x 128 receiving electrodes creating a 2D array of 16384 elements over the 32×32 mm transducer (16 elements/mm2), capable of detecting very small defects. dolphitech delivers transducers with different frequency and coupling material (delay line). View the chapter about Transducer Modules to see what we can offer.
The transmitting electrodes cross the receiving electrodes in a 90° angle. In between the transmitting and receiving electrodes, there is a piezoelectric material that generates the ultrasound.

To collect a pulse-echo-signal from a transducer element, a 70V pulse is excited on the transmitting electrode creating a sound field along the entire transmitting electrode, hence across all the receiver electrodes. The ultrasound goes through coupling and/or material and the reflected pulse is sampled on only one receiver electrode. Hence, the sampled pulse only represents one transducer element, which is the cross between the transmitting and receiving electrode.

Ultrasound Visualisation

An ultrasound Visualisation image is based on ultrasound reflections. The figure below shows an illustration of ultrasound reflections with a dolphicam2 transducer module. The dolphicam2 transducer has 16384 transducer elements. Each element works as a speaker and microphone. When a transducer element sends ultrasound, it travels through the coupling medium and into the material to be inspected.

1000

Whenever the sound meets a material with different impedance, the sound is reflected. The different acoustic impedance in the materials influences how much is reflected.

The most common damage/void can be air, where typically more than 99% of the sound wave is reflected. The figure shows two reflection cases, where one has a reflection from the back wall of material and one where the reflection is from a void. Both cases have a penetration echo that occurs between the coupling medium and NDT material.

In the back-wall reflection case, you can see that the reflection comes later, but in the void reflection, the reflection is earlier. The amplitude of the reflections depends on sound attenuation in material as well as distance travelled for the sound beam.

How IS A-Scan Performed

Each transducer element gets an electronic signal that is digitalized and represented in an A-Scan.

How IS B-Scan Performed

B-Scan is created by many A-Scans put next to each other represented by 1D-Array of transducer elements and shows you a cross section of the material you are inspecting. The B-Scan is generated using a color scale, where high amplitude values are given one end of the color scale. In image below, you can see a B-Scan where high amplitude values have the color white, and lower amplitude values are dark. In a B-Scan you can view the depth of the reflections, hence the depth of voids or damages.

How is C-Scan Performed

The C-Scan amplitude image is created from the maximum amplitude of all the B-Scans in from your transducer and gives you a view of looking directly into your material from the inspection side. For dolphicam2, you can imagine that your picture is based on the maximum amplitude value of 128×128 A-Scans (16384). Each amplitude value is given colour from a colour scale.

How is C-Scan Time-Of-Flight performed

The C-Scan time-of-flight image is created from the time-of-flight value of the maximum amplitude of the A-Scans from your transducer and gives you a view of looking directly into your material from the inspection side. The colours of the image show you the depth of the reflection or void. As with the amplitude C-Scan, you can imagine that your picture is based on the time-of-flight value of the maximum amplitude of 128×128 A-Scans (16384). Each time-of-flight value is given colour from a colour scale.

How is a 3D Image scan performed

The 3D images are based on the time-of-flight values but can be presented both as 3D amplitude image or 3D time-of-flight image. The 3D image gives you an excellent Visualisation of your damage.

Stitch View

This view shows the ultrasound image of a larger stitched area. Select what kind of stitching you wish to perform. And adjust settings and control for the stitching. more about stitching.

A-Scan View

Screenshot A-Scan

The A-Scan view shows the A-Scan only for a detailed view. It has two modes - Thickness measurement, which act as a thickness gauge, and a velocity calibration mode, where you can calculate the velocity of the material you are inspecting.

You can also enter this view from the velocity menu, and then clicking "calibrate", which opens the A-scan view in "Velocity calibration"-mode (see image under).

Screenshot A-Scan
A-Scan view configuration pop up menu:

The A-Scan View Configuration menu lets you select what features are shown and enabled in the A-Scan View. It is possible to show or hide Gates, threshold and measurement controls. It is also possible to choose if gates and threshold controls can be adjusted in the A-Scan view. These two options are mutually exclusive.

The panel provides buttons for 0%, 40% and 80% threshold value.

It is also possible to adjust the opacity of both gates and threshold lines for optimal visualiza-tion.

The “Show measurement” button will show an indication of either depth or thickness at the current a-scan position. The selection of depth or thickness is controlled by the Time of flight C-scan mode in the Gate Control Panel.

Please note: this option is only active when a A-Scan is viewed with other scans i.g.: C-Scan amplitude view.

Color Scale and Focus

The colour scales show you the colours used in the C-Scans. For C-Scan amplitude, the colour is spread out from 0-100%. For C-Scan time-of-flight, the colour is spread out on the depth of your scan (selected under coverage). By default, the colours in colour palette are spread evenly over 0-100% in Amplitude images (C-Scan and B-Scan), and over the complete depth in time-of-flight images.

By using the colour focus sliders in the top and bottom of the colour scale, it is possible to compress the colour scale over a selected amplitude span or depth-span. This is a very good technique to get clearer contrasts in your images if your reflected pulses are less than 100% of the dynamic amplitude range, or if the depth of your scan is larger than detected reflections. The combination of a certain colour palette and colour focusing can help you extract certain damages/defects in your inspected material.

Example Report

Scan TRM | Activate TRM

The GUI scan button does the same thing as the physical button on your transducer module (TRM). It makes it easy to operate the TRM from the Software in cases you are not holding the TRM. The physical scan button and the GUI scan button works smoothly together, so you can start a scan with one of them, and stop with the other.

Expand View | FUll-screen View


The expand button simply hides the top menu and settings menu and expands the ultrasound images. The different views the function/measurement buttons are still available. To disable expanded view, click/touch on the same button (arrow in button has changed direction).

Measurement tools | Inspection TAB

dolphicam2 software comes with several measurement tools for both B-Scan and C-Scans. Each measurement button will hide any other active measurements, except for the Reticle measure button which can be activated independently of other measurements.

Disable Measurement

Adjusting the B-Scan position inside C-Scan

You can choose where in the C-Scan you want the B-Scan cross sections by clicking/touching (moving) the cross-hair inside C-Scan.

  1. Click the disable measurement button
  2. When the button is black
    You may adjust horizontal and vertical cross-section for B-Scan (as shown in the illustration)

The disable measurement button turns off all measurements and enables you to set your B-Scan crosshair inside C-Scan, and enables you to change gating in the B-Scan Vertical by clicking/touching inside the B-Scan. View Gate chapter for functionality description of gating.

Rectangular Measurement Tool

Rectangular measurement button puts a rectangle overlay on the C-Scan. The rectangle can be moved by click/touch-hold-drag inside the rectangle, and you can change the size by click/touch-hold-drag on the edges or in the corner. Rectangle measurement values show up in the measurement panel.

The measurement (rectangular)

The measurement panel for the rectangular measure tool contains the size and dimension of the rectangle drawn over the C-Scan. It also has buttons for fine adjustment of the height and width of the rectangle. Additionally, the panel shows statistical data of the c-scan inside the rectangle. The statistical values are the mean, median and mode of the depth inside the rectangle if in Time of Flight-mode, or mean, median and mode of amplitude inside the rectangle if in Amplitude mode. It is possible to adjust the visibility of the measurement values next to the tool in the c-scan by adjusting the value on the “visibility of measurement information” slider.

Rectangle measurements: Statistical data:

Circular Measurement Tool(Circle)

Circular measurement button puts a circular overlay on the C-Scan. The circle can be moved by click/touch-hold-drag inside the circle, and you can change the size by click/touch-hold-drag in the edge of the circle. Circular measurement values show up in the measurement panel.

Measurement panel (Circular)
Circle Measurement Tool

The measurement panel for the circular measure tool contains the size of the circle (area, circumference, and diameter). It also has buttons for fine adjustment of the diameter of the circle.

Additionally, the panel shows statistical data of the c-scan inside the circle.

The statistical values are the mean, median and mode of the depth inside the circle if in Time of Flight-mode, or mean, median and mode of the amplitude inside the circle if in Amplitude mode.

It is possible to adjust the visibility of the measurement values next to the tool in the c-scan by adjusting the value on the “visibility of measurement information” slider.

Circular measurements: Statistical data:

Drill Hole Measurement Tool

Circle Measurement Tool

When the user selects a drilled hole measure tool, the measurement panel displays the damage size, drill hole dimension and circumferential damage of the drill hole. The drilled hole dimensions and the circumferential damage can be adjusted using both the measurement panel and touch-hold-drag over the drill hole tool in the C-Scan. The measure tool can be set into the position of the drilled hole by using the control circle. Drilled hole measurement values show up in the measurement panel.

Measurement pannel (drilled hole)

The measurement panel for drilled hole contains the radial size (difference in radius between inner and outer circle), the circumferential arc (length of the arc of the outer circle between the sectors) and the circumferential angle (angle between the sectors). It is possible to adjust the size of inner and outer circle and angles with buttons inside the measurement panel.
Additionally, the panel shows statistical data of the c-scan inside the highlighted area of the drilled hole tool.

The statistical values are the mean, median and mode of the depth inside the highlighted area if in Time of Flight-mode, and mean, median and mode of the amplitude inside the highlighted area if in Amplitude mode. To change the colour of the highlighted area, change the “Area color” value in the measurement panel.

It is possible to adjust the visibility of the measurement values next to the tool in the C-scan by adjusting the value on the “visibility of measurement information” slider.

Circle Measurement Tool
Drilled hole measurements: Statistical data:

Line Measurement Tool

Line measurement button enables you to put line overlays on the C-Scan and B-Scan. You apply the length by click/touch-hold-drag. The line in C-Scan shows you the length and can be moved in any direction, while the line in B-Scans only can be moved vertically or horizontally, and shows you the depth and/or width of what you are measuring.

Linear measurement

C-Scan measure points

C-Scan measure points button enables you to put up to 10 individual markers in your C-Scan image to measure the depth in mm/inches/mils and amplitude in % at each point. You add a point by touching/click anywhere in the C-Scan. Then you can move that point around by touch/click and hold and drag. You can remove the marker by touch/click on the marker without holding. The measurement values of the depth and amplitude correspond to the colour values of the C-Scan and will change depending the gating and thresholding applied. That means that we measure the distance and amplitude of the point that has the highest amplitude within the current gate(s) that’s above the threshold for that gate (see the chapter on gates and thresholds). The depth measurements will also change if you change the delay parameter (see the chapter on delay)

C-Scan measure point:

C-Scan Focus measure point

The C-Scan focus measure point allows you to toggle on and off measurements for the current C-Scan focus (cross-hair) position. This measure point can be applied independently of all other measure buttons.

C-Scan Focus measure point:

Full Matrix Capture

When pushing the scan button (hardware or software) to stop scanning, a full matrix data set of the last frame is sent from the Black-Box to the computer. This means that you can select B-scans and A-scans using the C-scan focus tool, create new C-scans by adjusting gates and thresholds, adjust range (from zero to the range of the captured data set), and change color focus and color palettes on the frozen image on screen. It is also possible to save data set and its current settings to file.

Gain and TCG

INSPECTION | Transducer > Gain and TCG

Setting Input
Gain (Analog Gain) -40dB to 0dB Max gain is 0dB
TCG (Time Corrected Gain) 0 dB/µs to 10 dB/ µs TCG is enabled by GUI button click/touch TCG will stop at 0dB gain.

Gain increases the amplitude of your signal, but also the noise level. The analogue gain and the Time Corrected Gain can be set using this menu and adjusts gain in the analogue front-end electronics in TRM. If the TCG option is disabled, the analogue gain controls the gain for the whole duration of the A-Scan.

If the TCG option is enabled, the gain can be increased during the A-Scan with a slope that can be adjusted with the input controls. The TCG range is from 0 dB/µs to 10.0 dB/µs. If the total gain (analogue + TCG) reaches more than 0 dB during the A-Scan/B-Scan depth, the gain will remain at 0 dB for the remaining part of the A-Scan/B-Scan.

By clicking on the detailed button, the TCG slope of the A-Scan can be adjusted by adjusting the blue points on the A-Scan signal in the Detailed TCG window. The TCG gain level of individual points is visible on the top of the detailed window. The number of TCG points on the detailed TCG window can be increased/decreased using the resolution control. The TCG window can be docked and undocked on your tough pad screen.

Tx ElemEnts(Aperture)

INSPECTION | Transducer > TX Elements (Aperature)

Setting Input
TX ELEMENTS(APERTURE) 1, 2, 4, 8, 16, or 32

This controls how many transmitting electrodes that are active for each of the 128 transmitting lines. The available values are [1, 2, 4, 8, 16 and 32] active electrodes. A higher number of electrodes gives a higher energy ultrasound pulse than a lower number of electrodes. Transmitting on more than several electrodes creates a focused area under the centre of the electrodes where the ultrasound energy is higher in the middle at a certain depth-range.

Transmitting on many electrodes (16, 32) will create a wider beam in the near field where your C-Scan image might stretch out the object in one direction. Increasing transmitting elements is a great way to increase signal amplitude without increasing noise. Hence, increasing signal-to-noise-ratio (SNR).

Example of 4 Transmitting elements:

610

SIGNAL Averaging

INSPECTION | Transducer > Signal Averaging

Setting Input
Average 1, 2, 4, 8, 16, or 32

This setting controls how many times the signal pulse for each transducer element is averaged. Hence, how many times you shoot a pulse, record signal, and add them together. The transducer module will transmit and record the set number of times for each element, and the result will be the average from these data sets. A higher number of signal averaging will result in lower noise levels, but also fewer frames per second.

Example signal averaging 1 vs 16

Transducer Pitch

INSPECTION | Transducer > Transducer Pitch
The pitch of a transducer is the spacing between the centres of the individual elements. The default pitch between two transducer elements is 0.25mm. By changing the pitch neighbouring elements are grouped together resulting in larger transducer elements, which will give more penetration into the sample along with an increased frame rate.

While using a lower frequency transducer of 1.5MHz the default pitch will be 0.5 mm.

This functionality is useful to view composite materials such as GFRP (Glass Fiber).

Image under is a sample of wind turbine blade, same are with 0,25 mm, 0,5 mm and 1 mm Transducer Pitch:

Pulse Length

Dc2 Transducer Menu: pulse length

INSPECTION | Transducer > Pulse Length

Setting Input
Pulse Length 5,00ns – 630ns

Resolution is 1/200MHz (5,00 ns)

This setting controls the length of the high voltage pulse that goes into the transducer and generates the ultrasound. The setting has a range from 5,00 ns to 630 ns. Each transducer type has an optimal input pulse to obtain a wide frequency range with high amplitude. Therefore the system detects the TRM type (example TRM-BA-2.25MHz) and sets this optimal input pulse. However, the pulse length can be modified to manipulate the signal and frequency content of the ultrasound. The pulse has a certain rise-time and fall-time which depends on the load of the transducer. Typically rise/fall time is around 6-9ns.

Illustration pulse length:

Coverage menu

Delay

INSPECTION | Coverage > Delay

Setting Input
Delay 1.00µs – 81.90µs

Delay is the time between the start of the transmitting pulse and the start of the sampling of data. This will typically be set to a fixed value for each transducer type, depending on the type and thickness of the coupling pad.

Upon adjusting the delay, the peneration echo (between the coupling and material for inspection) which is fixed at 0mm, can be adjusted along the required range. Other cases where you want to adjust delay is when you use a coupling shoe/wedge or water-box.

Grapichs showing how delay works

Range

INSPECTION | Coverage > Range
Setting Input
Range Velocity-dependent:
0mm – 120mm @velocity 6000 m/s

0mm – 60mm @velocity 3000 m/s
Zero Offset -/+ desired value

This setting controls the range/depth of your inspection, hence how long each A-scan/B-scan will be and the range in which your C-scan is created from. A default range is set according to what transducer type you have as the thickness of your coupling sets when your second echo from coupling occurs.

Explainer for zero offset

Zero Offset

Explainer for zero offset

Upon normalization, the penetration echo is placed at zero point on the ruler. The zero offset control can be used to manually adjust the zero point on the ruler, independent of delay, to another echo of interest. This can be useful in cases of inspection of materials with coating, where the inspection depth needs to be calculated excluding the coating.

Velocity

INSEPCTION | Coverage > Velocity

Setting Input
Velocity Manual (100m/s – 20000m/s)
Pre-configured speed list:
Aluminium, 6320
Brass, 4280
Copper, 4600
CFRP (Carbon Fiber), 3070
GFRP (Glass Fiber), 2740
Glass, 4540

This setting adjusts the velocity in the material to inspect and influences the depth scales and measurements in the Software. The value can either be set manually by clicking/touching or writing the correct value or can be selected from a pre-defined list of know material with the corresponding Velocity.

Velocity calibration

Velocity of the material to be inspected can be calibrated by clicking on the ‘Calibrate’ button. This will lead to the velocity calibration window.
Here enter the thickness of the material to be inspected, place the first gate along the penetration echo and second gate along the second echo of desired thickness. Click calibrate to store the calculated velocity value in the velocity menu.

You can save the calculated velocity with desried name by using ‘Save to file’. This will add the saved velocity along with the predefined list in the velocity menu.

Note: in order to delete a velocity value you need to deselect it first(if selected).

Gates/Threshold

INSPECTION | Coverage > Gates/Threshold
As mentioned in the beginning of the user manual, a C-scan image is based on the maximum values from all the 16834 A-scans. The range of your inspection is set in Range configuration. Within this range, the start gate and end gate set the depth range of which the maximum amplitude values are selected for creating the C-scan image.

The easiest way to set start gate and end gate is to click directly in the B-scan Vertical image. If you want more accurate control of the gating, you can use the configuration menu at bottom right. The amplitude C-scan and time-of-flight C-scan has separate gating which is chosen by clicking/touching/touching the “Amp Gate” or “ToF Gate” button.

There is also a lock button that locks the relative distance between start gate and end gate and you can move this locked range up and down in range by adjusting Start gate. The width of the gate can be adjusted using the width control.

The gates can also be overlapped upon each other. Note that only the selected gate in the Gate menu, can be adjusted at a time in the B scan vertical or A scan view, the other gates will be disabled.

C-Scan Generation mode

The Time of flight C-Scan image can be represented in two ways based on gates:

Ampiltude C-Scan generation:

There is only one mode for Amplitdue C-Scan:

Threshold

INSPECTION | Coverage > Gates/Threshold
In addition to gates, it is possible to adjust the amplitude threshold for the creation of C-Scans. This means that only A-Scan values that are above the threshold value within the gate are selected for C-Scan creation. The threshold can be adjusted by touching/clicking in the A-Scan view of C(T), C(A) and full views. Dragging the threshold line up (or up/down if A-Scan mode is full) applies the threshold. For fine adjustments, use the threshold control in the Gates/Threshold settings.

Multiple Gates

It is possible to select up to three individual gates for both amplitude and time of flight C-Scan. Each gate has its own individual threshold that works only within the range of that gate.

To select more gates, you must select the gate settings (be sure that you are in the Inspection Tab, select Coverage Menu and Gates/Threshold menu item. First select number of gates (1, 2 or 3) in the “Gates” option. To adjust the individual gates or thresholds. Select the appropriate gate number in the “Select Gate” option.

Each gate can be locked, as previously described.

The gates can also be overlapped upon each other.

Note: that only the selected gate can be adjusted at a time in the B-Scan vertical or A-Scan view, the other gates will be disa-bled.

The figure below identifies the various gates and thresholds.

Gates and capture method


INSPECTION | Coverage > Gates/Threshold

Setting Input
Capture Method Maximum Absolute Value

Maximum Positive Value

Maximum Negative Value

Capture Method controls whether C-scan is generated on maximum absolute value (max negative or positive), maximum negative value or maximum positive value.

In many cases, the pulse is symmetric around zero, in which case the maximum positive and maximum negative value are the practically the same. This results that some cases that it is coincidental will choose between maximum negative versus positive. This causes inaccuracy in time-of-flight. In this case, it is better to choose either maximum positive or maximum negative value. In cases you know which polarity of your reflected signal is superior, you should select the corresponding capture method.

The capture method for individual gates can be set through this menu. A common capture method can also be set for all gates by clicking ‘All gates’ button which will set them to selected capture method.

Gates/Threshold during FMC

When the system is in FMC data mode, either after stopping the scan, or loading from file, gate and threshold values are not updated continuously, as opposed to streaming live data. In the B-Scan and A-Scan views, the values are only updated on touch release/mouse button release. When adjusting gates and thresholds using the gate/threshold setting window, the changes are applied in approximately 1-second intervals. This is to avoid that the system becomes unresponsive due to the size of the data that needs to be processed by the computer CPU.

Transducer area

INSEPCTION | Coverage > Transducer Area
The user can change the area of a scan of the transducer in order to get a closer view of the sample being examined along with an increased framerate. For example, while inspecting drill holes in carbon fibre, it gives a closer view of the drill hole and the delamination area. There is a set of predefined transducer area that can be selected depending upon the required inspection area for the examination.

Pulse Retrigger time

INSEPCTION | Coverage > Pulse Retrigger Time
Pulse retrigger time lets the user adjust the time between pulses. This feature can be useful to clean up the image by removing multiple echoes in materials with little attenuation.

Signal & image menu

A/B scan mode

INSPECTION | Signal and Image > A/B Scan Mode

Setting Input
A-Scan Mode Full signal
Absolute value of the signal
Envelope of the signal
B-Scan Mode Full signal
Absolute value of the signal
Envelope of the signal

This setting selects how the A- and B-Scans are presented in the GUI. There are three ways of displaying the A-Scan and B-Scan: Full, Absolute and Envelope.

Full mode

Full mode displays the signal as it is. This gives you a detailed view and understanding in A-Scan where the signal is symmetric around 0 %. This mode does not make as much sense in B-Scan.

Absolute mode

The absolute mode takes the absolute value of the signal, hence there are no negative values. This still gives you some details of the signal behaviour.

Envelope mode

Envelope mode lays an envelope over the absolute maximum signal. This makes the interpretation in A-Scan and B-Scan easier.

Colour palettes

INSPECTION | Signal and Image > Color Pallets

Setting Input
Color Palettes:
  • C-Scan Amplitude & B-Scan
  • C-Scan Time-Of-Fligth
Jet
Gray
Gray Inverse
Autumn
Bone
Winter
Rainbow
Ocean
Summer
Spring
HSV
Pink
Hot

This setting selects which colour palette to use in C-Scan and B-Scan Amplitude C-Scan and B-Scans share one palette, and ToF-C-Scan has a separate palette. Which palette you adjust is controlled by clicking/touching the Amplitude or ToF button in Color Palettes menu.

Digital FIR filter

INSPECTION | Signal and Image > Digital FIR filter
Digital filters are widely used in signal processing to remove or to keep certain components of the signal. The LPF allows the low frequency to pass and filters out the high frequency; in other words, all portions of the signal that change rapidly are filtered, such as noise.

The scaling factor is used to scale the cutoff frequency of the filter. LPF smoothens out the rapid changes in the intensity of the pixels in an image. The low-pass filter affects the noise more than it does the image. By suppressing the noise, gradual changes can be seen that were invisible before. Therefore, a low-pass filter can sometimes be used to bring out faint details that were smothered by noise.

In dolphicam2, we have different low pass filters for transducers with an adjustable scaling factor. We have low pass filters with cut off frequency ranging from 0.5 MHz to 11MHz. The default scaling factor is set to 1 for all low pass filters, that can be adjusted with the controls on the user interface.

Image filter

INSPECTION | Signal and Image > Image filter

Setting Input
Image Filter (C-Scan Amp & ToF) None
Gaussian
Median

Image Filter can be applied to both C-Scan Amplitude and C-Scan Time-Of-Flight. These are basic image processing filters from OpenCV.

Gaussian filter

Gaussian filter smoothens the image and reduces noise. Gaussian filtering is done by convolving each point in the input array with a Gaussian kernel and then summing them all to produce the output array.

Median filter

The median filter runs through each element of the signal and replace each pixel with the median of its neighbouring pixels.

Filters compared

Total Focusing Method

user manual

INSEPCTION | Signal & Image > Total Focus method
Total Focusing Method can be applied on FMC mode (i.e., either on stop scan or on a FMC file). In the menu, upon switching ‘ON‘ TFM (Total Focusing Method) the focused data is displayed on the B-Scan vertical and B-Scan horizontal based on the position of the cross-hair line on the C-scan. Under Front pad menu, enter the velocity of the coupling pad and its thickness. Also enter the velocity of the inspection material. The software can process total focusing of the data by two methods: either by the CPU or the GPU (if any present in the computer).

A progress indication on the top right corner of the GUI represents the progress of the total focusing on the data. Each time the crosshair line is moved, or any other setting like thickness and velocity - it will trigger a new total focused B-Scan.

TRM Normalization

INSPECTION | TRM Normalization > TRM Normalization
Normalization is the process of removing unevenness in the coupling. So, if the coupling has variations in thickness and amplitude across the transducer surface, the normalization process will adjust the signal of each of the 16384 elements so that the front echo peak of each element is at the same sample position, and that the amplitude value of each element is the same.

Note: normalization only takes a few seconds.



Normalization is required

Normalization of a Transducer module (TRM) is required after a software update, or if your transducer module has not been connected to the Toughpad/PC before.

It is also a good habit to normalize the system before each new inspection. If the software detects that the connected TRM needs to be normalized, the software will prompt a normalization.

A normalization window is opened with the following instructions:

After first initial normalization, it is possible to normalize by going to
INSPECTION ->TRM Normalization > TRM Normalization.

A control panel pops up that lets the user redo the normalization or turn it off. There are three scenarios where turning off the normalization can be useful:

  1. If you have a TRM without delay line
  2. R&D applications
  3. Troubleshooting
    If you observe strange/irregular C-Scan or B-Scan images, turning off normalization can reveal if the previous normalization had a problem. For example, the delay line could have had residue of gel or water while the normalization was performed. If so, a new normalization with a dry and clean delay line is needed.

The Normalization procedure is the same as described in the TRM Calibration menu window.

You can also disable both Time-of-Flight Calibration and/or Amplitude Calibration by clicking/touching the “Time of Flight Calibration/Amplitude Calibration” buttons. Disabling calibration might be useful for R&D applications, but we recommend to never disable calibration during NDT measurements.

User Preference

INSPECTION | User Setting > Measurement Units Under User Preferences, you can adjust settings for Measurement Unit.

Setting Input
Measurement Unit Millimeters
Inches
Mills

Measurement units are just to set your preference of what unit you want scales and measurements should be displayed in.

Stitching menu

Stitching configuration segment has the configurations; Two and One Axis Encoder Stitching, Manual Stitching, GridTool Stitching. The stitching functionality is to easily create ultrasound images that are larger than the transducer front end.

Note: The image filter is set to none, when using stitching mode. It can be manually reset to preferred image filter type if needed, but it will cause the corners of the image to be cut off. The image filter will revert to default/selected type when changed to other views.

When inspecting a large predefined area, the easiest way of using manual stitching is to follow the scanning sequence that you set up. Just follow the numbering and active tile (red blinking frame) during your stitching. Click the dolphicam scan button to start scanning, when you are satisfied with your image (good coupling) click to freeze the tile and the active tile moves to next number in your scanning sequence. Repeat this until your entire stitched area is completed.

Step by step Manual Stitching

  1. Set the size of your area you will stitch, in one of the following ways:
    • Select a pre-defined area in roll-down menu «Inspection Area»
    • Adjust “Height” and “Width” using the +/- buttons.
    • Click on the green arrows in the outline of your stitch area.
  2. Set «Tiles in View» to get a full overview over stitch area.
  3. Select the “Stitch Pattern” you want to do the stitch with.
  4. Set “Camera Rotation” according to how the camera is in reference to the Software GUI.
  5. Set the “Stitching Overlap” you have decided (default 6mm).
  6. Activate Pop-out window if desired (if stitch area is large, it is nice to see the enlarged pop-out).

The stitch sequence will be displayed for you. Whenever you click to freeze your C-Scan image, the image moves to the next tile in your stitch.
To reset your stitching canvas, click/touch the clear canvas button. All your tiles will then be deleted, and scanning sequence is started over.

Each tile in the stitch is as big as the transducer front (32x32mm). The tiles overlap by 7mm (default), which means that the tiles (centre-to-centre) are 25mm apart. The stitching overlap can be adjusted in stitching window. The camera should be oriented in the same angle for each image taken (this is relatively easy). If your C-Scan images are not perfectly aligned, simply move them around with click/tough-and-draw. You can also control the overlap on images by right-clicking (tough-and-hold) and selecting “Bring to front”, or “Send to back” (view the bottom image below).

Manual Stitching Tip

If you set your stitch overlap to 25mm (~1 inch) apart, you can prepare your measurement by marking your material for inspection with dots 25mm (~1 inch) apart in all directions, either by using a ruler or e.g. a silicon sheet with pre-cut holes in it. Using these predefined marks, you can easily aim at them using one of the lines in dolphicam housing. Doing this really simplifies and speed up your inspection.

Grid Tool Stitching

The dolphicam Grid Tool is a mechanical position device for the TRM that makes it easy and quick to inspect large areas. How to set up the Grid Tool is described in a separate manual.

The Grid Tool stitching in GUI works exactly like manual stitching, except that the overlap is fixed to 7mm so that each tile covers 25mm. Setup the stitching the same way as described in the manual stitching chapter. For each C-Scan tile, click the TRM button to freeze the image, and the C-Scan tile automatically moves to the next tile. Release the Grid Tool locking mechanism and move to the next tile according to your stitching pattern.

One axis Encoder Stitching

dolphicam2 is compatible with any common quadrature encoder systems like the ODI from JIREH, and the C-Clamp from Phoenix ISL.

The Encoder Stitching GUI is very much like the manual stitching GUI and Grid Tool stitching GUI.

Start by mounting the encoder system to the dolphicam2 TRM. If you use encoders like the ODI for JIREH, mark the stitching pattern you plan to do on your sample. Apply water or gel (or mixture) to allow smooth movement of TRM coupling. Follow the marked lines with TRM rolling the encoder wheel behind your TRM. For each lane, click the TRM scan button to freeze the image, and move over to the next lane. The Software GUI will automatically move C-Scan to the next tile. This can be overridden if you need to redo any of the lanes. A good idea to get this stable is to put a long edge (like a ruler) along the marked line so the TRM can follow this edge.

Accessories

Ultrasound Gel & Water

dolphitech recommends using water or ultrasound gel or a mixture of gel and water to obtain good acoustic coupling between the transducer coupling and the material for testing. Water can be applied by a spray bottle. Mixing a small amount of gel in your water spray bottle creates a nice smooth stickiness that keeps the coupling material on the desired area.
An example ultrasound gel we recommend is ECO SUPERGEL. This gel is not hazardous or flammable and is safe to use. We also recommend mixing a small amount of water in your gel in a separate bottle to make a gel that is more liquidly. Typically, ultrasound gel on the market is not hazardous or flammable in any way and is safe to use.

Teflon Tape – Corner Pieces

Teflon tape is a very good material to either protect the coupling by covering the transducer front with Teflon tape or as corner distance pieces to enable the transducer module to slide easily while scanning. Contact dolphitech sales for Teflon tape recommendation or corner pieces.

Encoders and stitching

Grid Tool

Grid tool is a dolphitech product for easy manual-mechanical stitching with both dolphicam1 and dolphicam2. Please contact dolphitech sales for a quote. The Grid Tool does not require any connection to the dolphicam2 system – the Software GUI easily sets up the stitching with Grid Tool (view stitching chapter under Software & Functionality).

Encoders x And Y tool

dolphicam2 has two encoder inputs and are compatible with quadrature encoder solutions. The connectors have screws on the side to safely secure the encoder connection.

Cleaning and Maintenance
We recommend keeping the dolphicam2 system (both TRM and BB) clean for longer durability and to avoid system failure. All necessary cleaning and maintenance are described in this chapter.

Cleaning TRM & BB

We recommend cleaning BB and TRM housing if it is exposed to anything that may cause stains—such as dust, dirt, ink, paint or oil. Turn Off the BB and TRM as well as Toughpad and disconnect it from the Toughpad or PC. It is not necessary to disassemble the BB from Toughpad. Wipe it off/clean it with a soft, lint-free cloth moistened with mild soap water. Do not use solvents of any kind. Avoid getting dirt into openings. Don’t use aggressive cleaning products or compressed air.

Use air spray to remove dust and contamination from connectors and heat sinks on both BB and TRM. Connectors that are not in use should be covered with plastic caps that follows the BB system.

Cleaning the Transducer Front

Disconnect the TRM from the BB. Put a drop of mild dishwasher soap on the transducer pad and rub it gently with the tip of your finger. Dip your finger in water and rub on pad until soap is gone. Make sure the Transducer Pad isn’t scratched or damaged. Moist a soft, lint-free cloth with water and wipe off excessive water carefully.
