Paper Abstract

Angiocardiographic methods of determining left ventricular volume are well established, but the amount of labor involved in any manual procedure reduces the applicability of these techniques to myocardial function studies. An automated method of ventricular volume computation from unaltered x-ray images is clearly needed. This capability is offered by the amalgamation of state-of-the-art radiographic equipment with sophisticated programmable film readers. Problem areas are many, but primary attention should be paid to methods of determining boundaries for the objects in question from x-ray images and to utilization of accurate volume computation algorithms. Preliminary investigations in these areas are reported involving maximum likelihood estimation of boundary location and modified Simpson integration volume determination.
