Abstract

Many specific diagnoses of diseases of the heart can be obtained in cardiac catheteriza tion laboratories. Dynamic changes in volume and distributions of coronary blood flow are studied by means of injecting roentgen-opaque (i.e., x-ray dense) material into the left ventricle or the right ventricle through a catheter. At the time of the injection of contrast media, the chest of the patient is irradiated with x-ray and dynamic movements of the opacified heart are projected onto a fluoroscopic screen and then recorded on videotape by a television system or on film by a photographic system. Although cine roentgenography that using film) can have higher spatial and temporal resolution (Ref. 1) than video roentgenography (that using television), the cine systems require a longer time to complete the diagnosis since the film must be developed.
