Abstract

Three-dimensional images of physiologic data or models of data can be projected on a conventional oscilloscope by a computerized technique. The computer directs the X and Y deflections of the electron beam to a designated location on the oscilloscope face and modulates the beam intensity at that position to create a half-tone dot. By moving the beam in a programmed, incremental fashion, with appropriate changes of intensity, known patterns with varying shades of gray can be used to create a three-dimensional impression. We have used this method and data from orthogonal roentgen videoangiograms to generate simulated three-dimensional images of the left-ventricular chamber at end-systole and end-diastole, and to display scintigraphic patterns of pulmonary blood flow obtained from experimental animals after injections of radioactive microspheres into the circulation during exposure to normal and increased gravitational-inertial force.
