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. Collimators with different apertures are arranged on the fan-shaped collimator. The disadvantage is that the three inlaid rotary rings reduce the treatment Space reduces the treatment range of the collimator's rotation, increasing the difficulty and cost of equipment manufacturing; the collimators in the fan-shaped collimator are distributed in a fan-shaped area that is less than 90 degrees in the radial direction and less than 60 degrees in the axial direction, so that The collimation body can only accommodate one set of shielding plugs and collimators of two specifications. For patients with multiple lesions of different sizes, continuous and effective radiotherapy cannot be achieved, which limits the range of indications for selection.

Abstract

The present invention relates to radiotherapy apparatus and is especially one kind rotary focused gamma-ray radiotherapy apparatus. The rotary focused gamma-ray radiotherapy apparatus includes a radiator, a treating bed, a rotary rack, a rotary bearing ring, a rotating ring, a source body with radiating source and a cylindrical collimator set between rotary bearing ring and the rotating ring. The radiating source has the ray beam outlet located on the common focus in the rotating axis, and the collimator is connected through a transmission part with at least one spiral transmission mechanism and has several radiating passages with collimating unit and shielding stopper distributed corresponding to the radiating source. The present invention has expanded treating space, lowered manufacture cost and less manufacture difficulties, and may be used in the continuous effective safe radiotherapy of several disease focuses.

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...
