[0002] As one of the three major means of tumor treatment, radiotherapy has entered the era of precision, namely precise positioning, precise planning and precise implementation. The key to precise treatment lies in precise implementation. How to reduce or eliminate rotation errors caused by patient muscle tension, pain or differences in positioning habits of different doctors during radiotherapy has become the most difficult problem for radiotherapists every time they perform treatment.

[0003] Currently, the most widely used method is to fix the patient with a heated plastic film on a positioning body plate. When treating patients with chest, abdomen and pelvic tumors, the patient is also required to cross his hands on his forehead, put the body film on the patient and fix it on the treatment bed. The heated plastic film is easily separated from the plate after repeated use, affecting the patient positioning effect. The position of the patient's hands, neck and legs is difficult to evaluate and cannot be quality controlled, which may cause a large change in body position, affecting the quality of treatment and bringing great uncertainty to precise radiotherapy. Therefore, a radiotherapy body plate device with a rotation error correction function is proposed to solve the above problems. Utility Model Content
