Abstract: A control panel, which includes a programmable electroluminescent touch screen, is mounted so as to be operable by the radiologist during a PTCA procedure. The system has the capability of displaying, for comparison purposes, synchronized comparable images of the arterial blood flow before and after the PTCA procedure. Synchronized image is achieved by adding or deleting video frames from the end of a patient's cardiac cycle.

Abstract: A control panel, which includes a programmable electroluminescent touch screen and a joystick, is mounted so as to be operable by the radiologist during a PTCA procedure. A bedside monitor displays fluoro and roadmap information during the procedure. The radiologist can adjust the relative weight of the roadmap information to the fluoro information by operating the joystick. The system automatically selects the appropriate roadmap based upon the angular orientation of the camera gantry, or alternatively selects the appropriate gantry position to correspond to that used to produce a satisfactory roadmap.
