A computerised method of determining ventricular volumes from cine-angiograms in two planes was developed. The heart is divided into a large number of sections by computer analysis, the volumes being obtained from the corresponding diameters in the two planes. Using a computer markedly facilitates calculations and the results are immediately available. Data for ventricular and stroke volumes agree well with those reported in the literature.
