Microcomputer-based system for automatic analysis of M-mode echocardiograms

A microcomputer-based system has been developed for automatically analysing M-mode echocardiograms. This system can be used on images directly transferred from an echograph to the microcomputer. To obviate the major disadvantage of echocardiography, its poor signal-to-noise (S/N) level, the system conducts, first, an image restoration based on the quasi-periodicity of cardiac cycles, then border extraction is performed, using methods based on template matching using dynamic cardiac information present in the echocardiograms.
