Testing equipment
Aquarium
The dimensions are determined in accordance with the focusing distance of the transducer. The tank must be transparent to be able to see what is being under test.
Phantoms
Ultrasound phantom models are used to reproduce the propagation variations observed in tissues.
Propagation medium
The propagation medium is chosen so that: waves can propagate easily, there is an impedance matching with the piezoelectric, it is similar to tissues generally under observation.
