Abstract
A completely automated procedure for the extraction of the outline of the opacified left ventricle from digitized serial angiocardiograms is described. This represents the major problem in the development of completely automated procedures for the quantitative analysis and interpretation of clinical angiocardiograms. The approach differs from previous work in posing the problem of outline or contour extraction as one of minimum cost tree searching. Branch metrics are defined which are indicative of the likelihood a particular branch lies on the true contour. The branch metrics incorporate both local and global or contextual information. The most likely path or contour is then extracted by a novel application of the Viterbi algorithm.
