Abstract
Received ultrasonic scattered signal expressions are presented for the case of an individual scatterer moving through a Gaussian beam pattern. The return signal is of a burst-like nature and oscillates as a function of time under a Gaussian amplitude envelope. Results are presented to show specific parameter dependence on the scatterer motion and beam configuration to aid in the use of the technique of ultrasonic scattering for detecting and monitoring the motion of emboli formed in blood during decompression or open-heart surgery.
