Radiation therapeutical irradiation device

Abstract

The invention discloses a radiation device of radiation treatment through rotating focus of gamma ray, which comprises the following parts: rotary ring, source bulk and detector, wherein multiple radiation sources are set in the source bulk, which emits ray to focus on the public focal point on the shaft line of rotary ring, one end of source bulk and detector is connected on the rotary ring, which are distributed symmetrically along radial direction of rotary ring, the high-activity treating radiation source and low-activity diagnosis radiation source are set in the source bulk, the beam of radiation source pierces the shaft line of rotary ring, the detector receives radiation information, which responds to output detecting information.

Description

technical field [0001] The invention relates to radiation medical equipment, in particular to a radiation therapy device for gamma ray rotational focusing. Background technique [0002] In the radiation therapy using the radiation therapy device, the working principle of rotating focus is used to rotate and irradiate the patient's lesion, so that the lesion tissue near the rotating focus point is irradiated with the maximum dose, and the healthy tissue is irradiated with an instantaneous and tolerated dose. Thereby killing the lesion, protecting the healthy tissue around the lesion, and achieving the purpose of radiation therapy. Chinese Patent Publication No. CN 1275410 discloses a radiotherapy device for multi-source radiation systemic therapy, which includes: a source body, a source body rotary ring fixed with the source body, a collimator, and a collimator fixed with the collimator. The collimator slewing ring, the slewing bracket, and the slewing support ring fixed in ...

AI Technical Summary

Problems solved by technology

[0003] The multiple radiation sources in the source body of the above-mentioned device are therapeutic radiation sources, and there is no real-time imaging system. During the treatment process, it is impossible to realize image detection, monitor the movement of the treatment target, and verify the radiation treatment dose, thus affecting the radiation focus center and the treatment target. Point coincidence accuracy, the treatment plan cannot be corrected according to the actual radiation dose received by the patient, and accurate radiation therapy cannot be achieved, which affects the effect of radiation therapy
