Research Abstract

A real-time 3D medical acoustic imager with a concave mirror and a small element array needs a wide contact area between a probe and the body surface, and thus the variation of fat content in the cutaneous fat layer is supposed to be larger than a conventional imagers, causing the severe deterioration of image quality by aberration. Therefore this method should employ an aberration correction technique to suppress the influence of aberration. This study shows that the transmit center frequencies of 1.5 MHz are suitable for aberration correction in the case of a fat layer 1 cm thick, and under severe aberration conditions the proper transmit frequency for the aberration condition is lower than half of that for imaging.
