11 March 1976 Clinical Application Of A Light-Pen Computer System For Quantitative Angiography

Quantitative angiographic analysis has been recognized as an important method for defining the hydraulic function of the heart. A video disc light-pen computer system has been devel-oped at Stanford Medical Center in order to facilitate quantitation of ventriculographic images (1). Development of this system was prompted by the need to provide measures of overall left ventricular pump performance on a routine basis for clinical decision making and to provide a method for implementation of new experimental approaches. This system provides the capability for computation of ventricular volumes and other measurements from operator-defined margins by greatly reducing the tedium and errors associated with manual planemetry.
