IPC: G01S7/52
Filed: 1986-10-15
Abstract: A method and apparatus of enhancing the accuracy of 
in vivo sound velocity estimation by identifying segments 
of different sound velocity along a tracked ultrasound 
beam. The effects of refraction on the tracked beam at 
the interface between tissue regions are estimated. Also 
disclosed is a technique for estimating the refractive 
effects of naturally occurring and artificially introduced
