Ultrasound field calculation in a water-soft tissue medium.
An efficient numerical approximation for ultrasound field calculation in a two or three layer water-soft tissue medium is presented. It is extended from a method developed previously in a homogeneous medium. The emphasis of this study is to examine the conditions that are required for this approximation. Criteria are given for achieving an appropriate accuracy, which is verified by comparing it with the Rayleigh integral.
