1 June 1971 Computer Calculation Of Left Ventricular Volumes From A Cineangiogram
Author Affiliations +
This paper is concerned with the automatic calculation of left ventricular volumes from a cineangiogram by a digital computer. It will first describe three digital techniques (1) to restore the original dimension of the objects by a logarithmic transformation, (2) to subtract images before and after the injection of radio opaque agent, and (3) to detect boundaries by a threshold method based on statistical principles and heuristics. Experimental results on several frames will be presented to demonstrate the feasibility of these techniques. Once the boundary of the ventricle is determined, the computation of the volume is performed by the usual Simpson's method.
