Abstract

The invention discloses a radiotherapy system, an application method and a CT scanning device control method, and belongs to the technical field of medical equipment. The terminal realizes integration of positioning and dynamic treatment through a cooperative control system of the CT scanning device, the patient positioning mechanism and the radiotherapy device. A scanning ring assembly of the CT scanning device supports sitting posture imaging, prone posture imaging and standing posture imaging through a horizontal / vertical displacement and around-axis rotating mechanism. The patient positioning mechanism is integrated with a multi-level telescopic supporting body and a centering adjusting system, pitching, rolling and rotating three-dimensional posture adjustment can be achieved, and the patient positioning mechanism is suitable for lying, standing and inclined body positions. The device breaks through the body position limitation of a traditional radiotherapy device, is suitable for an ion radiotherapy system, can replace a high-cost rotating rack beam system through the combination of the fixed beam treatment head and the multi-body-position patient positioning technology, achieves multi-angle irradiation and arc-shaped treatment while guaranteeing the treatment precision, reduces the equipment complexity and manufacturing cost, and is suitable for popularization and application. And the clinical accessibility of ion radiotherapy is improved.
