Abstract

Ultrasonic images of the heart, i.e. echocardiographs, have been in use in diagnosis and treatment for some time, the quality of the images is not good. This paper describes a procedure for enhancing and improving the quality of echocardiographs. The procedure described has three main aspects: noise filtering or smoothing, edge extraction and contour following. A number of filtering algorithms to eliminate noise and smooth the image are presented and their advantages reviewed. Several edge operators are considered and their merits discussed, and a modification to one is presented. Contour tracing algorithms are studied and a modification proposed. The resulting procedure is illustrated in each step.
