ABSTRACT:
An apparatus and method to generate low power ultrasonic, echograph images of selected stationary and moving target objects having high resolution. The apparatus and method include: an apparatus for transmitting a plurality of ultrasonic signals into a selected area of tissue, and apparatus for receiving the corresponding ultrasonic echo signals for each of the transmitted signals. A correlator autocorrelates and cross-correlates the transmitted and received ultrasonic signals. The correlated signals are summed, combined in ratios and partitioned into visibility amplitude data, visibility phase data, differential phase data, closure amplitude data and closure phase data for mapping. The preferred apparatus and method thereafter perform a non-linear image processing, either by an iterative side lobe subtraction signal processing procedure to remove signal noise and/or by an interative hybrid mapping signal processing procedure. The resulting data map yields a high resolution image of the selected target with more data and less noise. Signal processing to show motion or target object changes after noise reduction is also disclosed. In a preferred embodiment, the apparatus and method is employed as a clinical diagnostic tool for generating non-traumatic, high resolution imaging of bodily tissue.
