Description

Body adapting frame for mammary gland radiotherapy positioning bracket

Technical Field

The utility model relates to the technical field of radiotherapy positioning, in particular to a body adapting frame for a mammary gland radiotherapy positioning bracket.

Background

In the accurate radiotherapy of malignant tumor, the fixation of the body position of a patient can reduce the involuntary movement of the body position in the radiotherapy process, thereby ensuring that the actual irradiation range of the beam is consistent with the planned target area as much as possible, and the fixation of the radiotherapy body position is particularly important.

During radiotherapy work, patients often need to maintain a fixed posture for a long period of time, which often results in their muscles becoming stiff or uncomfortable. In order to alleviate such discomfort, the patient may involuntarily perform motion adjustments, which, although small, are sufficient to cause relative offset between the patient and the radiotherapy apparatus, thereby affecting the accuracy of the radiotherapy, reducing the therapeutic effect and satisfaction, increasing difficulty for the work of medical staff, and simultaneously, bringing additional pain and trouble to the patient.
