Abstract

A digital integrated radiotheraph system, the complex form source is installed in the bore of the containment shell, about 6 to 60 of source inner collimating devices wit h the axial center line pointing to the focusing point are installed in the inner of the source alongside the axial direction and circumferential direction, every source inner collimating device is installed along the circumference with same distance, the length and diameter of every source inner collimating device is equal to each other; there is complex form collimation unit in the inner of the source with the outer surface corresponding to the inner surface of the source, the inner surface of the collimation unit is the treating cavity with the fore-and-aft cut through with hollow circular ring shape, in the collimation unit there is a set of collimator connecting with the source collimator and heading to every source collimator with the number 2-8 times more than that of source collimator and wit h the axial center line pointing to the focusing point, the length and inner diameter of the inner collimation in the axial cross-section is not equal to each other, and the distance of the inner collimation in the axial cross-section from the focusing point is not equal to each other.

Description

technical field [0001] The present invention relates to medical devices. Background technique [0002] Cancer has gradually become the number one killer of human health, and the treatment of cancer is still dominated by surgery, chemotherapy and external beam radiotherapy. These three treatment methods all face a worldwide problem: how to destroy the diseased tissue without irreversible damage to the healthy tissue. Chinese patent ZL 96120531.8 discloses a radiation medical device, which guides thousands of beams of gamma rays to converge precisely at the focal point through rotating three-level collimation, and performs helical cutting radiotherapy of head stereotaxy and body stereotaxy , each single beam of radiation is a safe dose when it passes through the human body, and the dose at the focal point can be as large as a one-time lethal lesion tissue, realizing non-invasive radiation therapy. Since then, we have continued to develop, canceled the helmet, and made struct...
