Abstract

The application discloses a beam limiting device. The beam limiting device comprises a rotation collimator, wherein the rotation collimator comprises a truncated cone-shaped housing, a driving devicefor driving the truncated cone-shaped housing to rotate, an angle detecting device for detecting the angle of the truncated cone-shaped housing and a control device, wherein the truncated cone-shapedhousing is provided with a central cavity, and a plurality of rotation collimating holes which are different in hole diameters and are in parallel to a generatrix are formed in the side surface of thetruncated cone-shaped housing in a radial direction; and the control device is connected with the driving device and the angle detecting device, and is used for receiving a signal transmitted by theangle detecting device, and controlling the driving device to start or stop according to the received signal. Through the adoption of the beam limiting device disclosed by the invention, the collimator is applied, the driving device is jointly controlled by the angle detecting device and the control device to automatically rotate or stop, and the truncated cone-shaped housing automatically rotatesor stops along with the driving device to complete the replacement of a radiation field, so that repeatedly replacing the collimator is avoided, and the radiation field of the collimator provided bythe application can be conveniently, quickly and automatically replaced. The application also discloses radiotherapy equipment.

Description

technical field [0001] The invention relates to the technical field of radiotherapy, in particular to a beam limiter. The invention also relates to a radiotherapy device. Background technique [0002] Collimators are usually used as radiation head components of medical accelerators and are mainly used for radiation therapy of tumors. In the process of tumor radiation therapy, it is usually necessary to change the radiation field of view of the collimator according to different patients and different body positions, so as to perform radiation therapy on tumors of a certain size and shape in the patient's body without damaging normal tissues and vital organs. Therefore, it is particularly necessary to improve the collimator. [0003] The radiation collimation system of the existing medical accelerator is mainly composed of a primary collimator, a secondary collimator and an additional collimator, and the transformation of the radiation field is mainly realized by the additio...
