Abstract

The present invention discloses a radiotherapy radiation device and radiation method, which comprises source body(2), pre-collimate body(4), helmet(7), drive assembly and therapeutic bed(12), inside of the source body(2), multiple radiation source focuses ray along radial direction on a public focus on the center axis of radiation device, and the source body(2) and pre-collimate body are connected with drive assembly separately. The radiation method adopts system initiation, which enables the pre-collimate body(4) and helmet(7) to go through the steps of initial zero position, position locating and jointing end to end to implement radiotherapy. The advantages of which lie in the high focusing accuracy of the radiation source(3) and favorable therapeutic effect.

Description

technical field

[0001] The invention relates to a radiotherapy radiation device and a radiation method thereof. Background technique

[0002] The radiation therapy device adopts the working principle of rotating focus. In the existing radiation device, multiple radiation channels are distributed on the rotating source body, and there are radiation sources and pre-collimators in the radiation channels. The pre-collimator inside the source body is equipped with multiple groups of collimators with different apertures. Each group of collimators is distributed in the same way as the radiation channels on the source body. The apertures are focused on a common focal point, which lies on the axis of rotation of the source and collimator. Chinese patent CN1126622A discloses "A Method and Radiation Unit for Changing Radiation Beam Diameter", which is a method and radiation unit for changing radiation beam diameter in medical radiotherapy equipment. There are radioactive sources and ...
