Abstract

This paper describes a procedure for computer extraction of the aorta-ventricle outline from digitized single-plane left ventricular angiocardiograms and the identification of key anatomical features such as the ventricular apex and aortic valve line. Given this information, the estimation of volume is a relatively straightforward computational procedure. The procedure is completely automated requiring operator intervention only to initialize an angiocardiogram series. The aorta-ventricle outline is extracted by application of a heuristic tree searching algorithm. This algorithm proceeds sequentially, attempting branch-by-branch to assemble individual branches onto a most likely aorta-ventricle outline which is then provided as input to the volume computation routines. The procedure is shown to be computationally efficient and the results are consistent with outlines extracted by trained cardiologists. Examples of this procedure on selected angiocardiogram series are provided.
