Paper Abstract

A new radiographic system has been developed for use in mapping three-dimensional epicardial motion. The new radiograph consists of an array of detectors arranged such that they monitor 1 cm strip of scattering photons along a contour across the cardiac surface. Synthesis of the detector data permits immediate display of the beating cardiac contour on a CRT screen for observation and analysis. The entire radiographic system is under microprocessor control. Location of the cardiac surface and initial cardiac contour display is possible within ten seconds of a scan's initiation. The system has been carefully validated on mechanical models. Studies with anesthetized canines demonstrate the new radiograph in a physiological environment. Eventual clinical use is expected to provide the physician with accurate data on ventricular function at patient costs and radiation dose rates lower than those of other available techniques.
