An ultrasound simulator has been created to calculate the beam pattern of various array configurations. This simulator works either in the transmit mode or in the transmit/receive mode. It takes advantage of the computing and imaging display capabilities of the V-76 computer.
This simulator primarily addresses the problem of suppression of unwanted parasitic lobes. This can be achieved in various ways. This paper presents some simulated and experimental results of various array configurations while varying some parameters: element spacing, pulse length, effect of time quantization, effect of nonlinear processing of received signals, etc.
