Radiotherapy device

Abstract

The invention provides radiotherapy device, which includes annular frame bodies, a walking mechanism, a lifting mechanism, and a radioactive source. The bottoms of the annular frame bodies are fixed on a base. There are two annular frame bodies. The two annular frame bodies are arranged in parallel at a certain distance, the side surfaces of the annular frame bodies are equipped with annular rackslideways and annular guide slideways in parallel. The annular rack slideways of the two annular frame bodies are arranged oppositely, and the annular guide slideways are arranged oppositely. The walking mechanism is arranged between the two annular frame bodies. The lifting mechanism is arranged in front of the two annular frame bodies, and the lifting mechanism is integrated with the walking mechanism. The radioactive source is capable of adjusting an angle under the drive of a swing drive motor after being connected with a swing mechanism. The layout design of the overall structure is reasonable, which facilitates the installation of the walking mechanism and the lifting mechanism; and the added lifting mechanism does not occupy additional space of the equipment, so that the device canrealize the accurate positioning of the radioactive source by using an image positioning technology.

Description

technical field [0001] The present invention mainly relates to the technical field related to radiotherapy, and specifically relates to a radiotherapy device. Background technique [0002] Radiation therapy is the treatment of malignant tumors and some benign diseases by using one or more ionizing radiations. In the prior art, there are various types of equipment used for radiotherapy, including radiotherapy implemented by a treatment equipment with a ring structure. The above-mentioned radiotherapy equipment with ring structure is generally provided with a ring-shaped track, and the swingable radioactive source is installed in the track through a walking mechanism. For movement and swing, a small number of devices use three-dimensional motion control, that is, an axial control mechanism is added at the position of the radioactive source.

AI Technical Summary

Problems solved by technology

[0003] In traditional radiotherapy equipment with a ring structure, due to its structural characteristics, it is difficult to increase the radial adjustment structure of the radiation source, that is, to adjust the relative distance between the radiation source and the patient. Therefore, in order to enable the radiation source of the equipment to accurately irradiate It is necessary to adjust the human body support (such as a medical bed) at the same time. In the actual process, it is inconvenient to use and cannot be adjusted accurately. Especially when it is used with image positioning, it is difficult to achieve precise positioning and automatic control.
