In this paper, a wire-target technique was used for lateral beam profile measurements for a single-element, focused transducers in the very high-frequency range (35-60 MHz). Two wire targets made from 9-cm long tungsten wires with diameters of 8 /spl mu/m and 20 /spl mu/m were used as the pulse-echo targets to measure the lateral beam profiles at the focal plane of two single-element, focused transducers,...
