Abstract

The invention relates to a radiotherapy device for gamma ray rotational focusing. The invention includes a host controller, a driver, a radiation device, a treatment couch, etc. The treatment couch is installed on a slewing ring, a rotatable shielding body is provided on the radiation device, and a group of radiation sources having the same distribution law as the radiation source is provided on the rotatable shielding body. Through holes, the two ends of the slewing bracket are fixed with a slewing support ring, and the slewing support ring is axially positioned and rotated to cooperate with a slewing ring. The radiation device is arranged between the two slewing rings. A cylindrical collimator, the center of the collimator is provided with a source body, and the source body is equipped with a plurality of linearly arranged radioactive sources. Compared with the prior art, the present invention increases the range in the rotary ring due to the synchronous rotation of the cylindrical collimator and the source body in the radiation device, expands the range of movement of the treatment bed in the rotary ring during treatment, and expands the range of treatment. space, reducing the manufacturing cost and difficulty of equipment.

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 at 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 th...
