Radiation therapeutical device

Abstract

The invention relates to a radiotherapy device and method of gamma ray rotation and focusing, which comprises the following steps: main control unit, driver, radiation device, therapeutic bed and so on, wherein the therapeutic bed and rotatable barrier are set in the rotating ring and radiation device separately, the rotating support ring is fixed on two ends of rotating stand with the axial of rotating support ring matching rotating ring positionally, the relating radiation device is set between two rotating rings, whose the rotatable barrier center fixes a rotatable cylindrical alignment.

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 ...

Problems solved by technology

[0003] The multiple radiation sources in the source body of the above-mentioned device are therapeutic radiation sources. Without a real-time imaging system, image detection cannot be realized during the treatment process, nor can it monitor the movement of the treatment target and verify the radiation treatment dose, thus affecting the radiation focus center and The coincidence accuracy of treatment targets cannot correct the treatment plan according to the actual radiation dose received by the patient, and cannot achieve accurate radiation therapy, which affects the effect of radiation therapy

[0004] 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
