Abstract

Biplanar high-speed cineradiography a technique that offers a unique approach for obtaining precise physiologic data that extends beyond the conventional recording devices. The rapid frame rates reduce motion blurring of moving objects and when used in the biplanar mode allows the inves-tigator to examine this information in three dimensional space. In our laboratory we have found it to be a useful technique for examining cardiovascular dynamic changes, particularly those events which are difficult or impossible to describe or measure using standard cine or physiologic recording methods. " " When combined witha number of new radiopaque contrast materials the investigator can obtain in-formation about the changing size and shape of the cardiac chambers throughout the heart cycle; the patterns of flaw through these chambers and the surrounding great vessels; the motion of the heart valves and the correlation of this data with pressures, sounds or electrical events. This type of information enables the scientist working with a small laboratory computer to calculate rapidly changing forces, volumes, dimenfpns and flaws in the cardiovascular system.
