  • Title: [Quantitative cineangiography. Part I. Computerized volumetry of ventricular models (author's transl)].
    Author: Valli G, Balocchi R, Benassi A, Mariani M, Barsotti A, Balbarini A.
    Journal: G Ital Cardiol; 1977; 7(11):1088-92. PubMed ID: 924069.
    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.
