Abstract: Coronary perfusion apparatus in which a catheter is held in place in the coronary artery by an intra-aortic balloon. The catheter carries a pressure sensor which is positioned adjacent the heart valves. The pump supplies oxygenation blood to the catheter at a predetermined time in the cardiac cycle which exists downstream of the occlusion through openings in the catheter under the control of a synchronizing means which determines the time of perfusion in response to cardiac signals and to signals corresponding to the measurement mode by the pressure sensor.

Abstract: Elementary detectors constituted by juxtaposed crystals are scanned by two groups of photomultipliers: photomultipliers of energy each scanning an elementary detector and photomultipliers of rank each one scanning a crystal of predetermined rank in each of the elementary detectors. All the photomultipliers are connected to the primary computer.
