Modelling and Numerical Simulations of In-Air Reverberation Images for Fault Detection in Medical Ultrasonic Transducers: A Feasibility Study

Figure 7

In-air reverberation pattern for the 128-finger healthy medical ultrasonic transducer (the vertical numbers corresponded to the reverberations line and the horizontal numbers correspond to the number of elements). Signals 1, 2, and 3 on the right hand side correspond to the signal paths and reflections indicated in Figure 4.
