Two Dimensional Statistical Analysis of Synthetically Focused Images
In previous reports our group has described a novel approach to acoustic imaging (Berkhout, 1982; Berkhout et al, 1982; Mesdag et al, 1982; de Vries et al, 1983). The heart of this approach is formed by a computerized wave field extrapolation technique. By means of this technique the distortions due to the propagation of the acoustic wave are removed from the measured data. For medical purposes the acoustic wave field is scanned by a linear array operated in backscatter mode.
