Problems solved by technology

[0003] The rotary support of the above-mentioned device is provided with a rotary support ring, a source body rotary ring, and a collimator rotary ring. The disadvantage is that the three mosaic-suited rotary rings reduce the treatment space, reduce the rotation range of the collimator, and increase the Equipment manufacturing difficulty and manufacturing cost; the two ends of the source body and the collimator are connected to the slewing bracket through a slewing ring, and the minimum diameter of the slewing ring is one meter. Due to the large slewing rings of the source body and the collimation body, the manufacturing process is complicated , in the process of rotating and focusing the radiation beam, it affects the coaxial rotation accuracy of the source body and the collimator, thus affecting the focusing accuracy of the radiation source beam and reducing the effect of radiation therapy

Abstract

The invention discloses a radiation device of radiation treatment through rotating focus of gamma ray, which comprises the following parts: rack, rotary ring on the rack, source bulk around rotary shaft line and aligning bulk, wherein multiple radiation sources are set in the source bulk, which contains radiation source correspond to beam channel, the radiation source is focused on the public focus on the rotary shaft through radiation channel, two ends of source bulk and aligning bulk connect rotary ring and rack separately.

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 ...
