Bamber and Dickinson have developed a computerized tissue model. and have made statistical measurements of texture from simulated B-scans based on that model.. Flax et al. have also recently shown results from numerical modeling and measurements of B-scan image texture..

They are mainly due to the non piston-like behaviour of transducers and to the assumption of a rigid target (Rayleigh surface waves on the ball are neglected).

This paper presents some simulated and experimental results of various array configurations while varying some parameters: element spacing, pulse length, effect of time quantization, effect of nonlinear processing of received signals, etc.

There was representation from 14 nations, including England, France, U.S.A., West Germany, Canada, Italy, Japan, Poland, The Netherlands a

Since the high lateral resolution, high sensitivity and large angular aperture of a strongly focussed beam are qualities which are well suited to the detection and mapping of scattered ultrasound, C -scanning is a promising mode for tissue differentiation.

A rate of 800 frames/sec. has been reached for an image made of 1500 uncorrelated points. However more detailed images have been obtained with a frame rate of 400/sec. and a point number of 3000 In this case the resolution is 1 mm in depth and 2.5mm in width.
