Abstract
A simple technique for the determination of the spatial and temporal transmit-receive field distribution of spherically focused high-frequency transducers is described. In this study tungsten wires were used as echo-targets. Based on the scattering of sound on a rigid cylinder the transmit-receive field projection of spherical sources measured with a wire target was compared with both, theoretical pressure distributions and hydrophone measurements in the frequency range from 3 to 17 MHz. It was demonstrated that both techniques yielded comparable results for the low-frequency transducer, whereas only the results of the wire target technique were also in agreement with theory for the higher frequency transducers.
