Simulation equipment has been assembled. It can be used in various scenarios, and in different settings. It can have one or multiple chambers where every chamber can be filled with different medium. Its design fits the best with liquids, but it can be filled even with gas. Also, as shown in the picture, primary setup is with 2 ceramic actuators (one used for transmitting, and one used for receiving ultrasound waves), but it is not the only setup. It can be used with 1 ceramic driven by burst signal. Wholes on surface are custom drilled for inserting and moving sensors in positions calculated in advance.
