X-ray computed tomography system for tomographic representation of patient, has target materials applied on rotation plate, where focus point of bouncing focus bounces back and forth between two target materials

摘要

The system (C1) has an X-ray tube (C2) provided with an anode and a cathode, where the anode is provided with a rotation plate. Tube voltage is applied between the cathode and the anode, so that tube current is generated between the cathode and a focal point on the rotation plate. A bouncing focus bounces back and forth between rotating focus paths on the rotation plate, and target materials are applied on the rotation plate. A focus point of the bouncing focus bounces back and forth between the target materials. The target materials are selected from molybdenum, tungsten, aluminum, copper or chrome.
