MAUT Transducers (TRM)

The MAUT dolphicam2 transducer is formed by 128 transmitting electrodes crossing 128 receiver electrodes as you can see in figures 3 and 4. In between the layer of transmitting and receiving electrodes, is the piezoelectrical material that creates the ultrasound. The cross sections between each transmit electrode and receive electrode create the transducer element that results in an A-scan. Hence 16384 elements and A-scans. The majority of dolphicam2 transducers are 128 x 128 elements (2.5MHz, 3.5MHz, 5.0MHz, 8.0MHz, 10.0MHz), but they also offer a 64 x 64 element transducer (1.5MHz) and a 32 x 32 element transducer (0.7MHz).
dolphitech, has developed an MAUT platform called dolphicam2 (succeeding the first generation of dolphicam1). Figure 5 shows all the views that dolphicam2 provides with the volume data from MAUT. The example data is from an impacted sample of CFRP (Carbon Fiber Reinforced Polymer). These images show a result of a Matrix Array Transducer that has 128 x 128 elements. Hence there are 16384 A-scans. Looking at the views in figure 5, by moving the crosshair in the C-scans shows the corresponding A-scan in that point. The crosshair also decides where you want to slice your data and show the B-scan vertical and B-scan horizontal. The C-scan Amplitude (grayscale) is based on the max peak amplitudes in your data, giving you an incredibly detailed view of the pulse-echo reflected in your material. The C-scan Time-Of-Flight (color), provides the user with a very precise view of the depth and thickness of the reflected pulse echo. Lastly, there is a 3D view which can be zoomed and rotated to give a very intuitive representation of the data.
