The unabsorbed parts of an X-ray beam from a tube pass through the patient, who lies on an X-ray transparent table, and strike an image intensifier. The resultant image is detected by a video camera and fed to a video amplifier. A central unit controls a high voltage generator causing the tube to emit bursts of X-rays at intervals while an injection assembly introduces the fluid into the patient's...
