Piezoelectric ultrasonic transducers are widely used in many fields, such as medical ultrasonic, nondestructive
testing and structural health monitoring. The limits of piezoelectric bulk ceramics in high
electromechanical coupling, broad bandwidth, good acoustic impedance matching and high resolution
of acoustically separated elements lead to attention on piezoelectric 1-3 composites with...

At KIT a 3D USCT system is under development. The system is optimized for SAFT imaging and has a multistatic setup of 2041 ultrasound transducers with approx. 1MHz 3dB bandwidth and 36° 3dB opening angle for 2.5MHz. The USCT groups transducers in a semi-elliposoidal aperture surrounding a ROI of 10x10x10cm$^3$. To increase the ROI for a next USCT generation, the opening angle of a future...
