Abstract

A computerized system for cineangiograms analysis is described. Each selected frame is displayed by a TV camera on a TV monitor, allowing the physician to draw the left ventricular contour using a light-pen. The coordinates of selected points are sent to a small size digital computer to be processed. The processing techniques are outlined, while particular evidence is given to the operating procedure. Left ventricular volume is evaluated using both area-length and slice methods. Results obtained on models yield an estimation of the accuracy of the volume measurements.
