Abstract

The invention provides image-guided radiation treatment equipment. The image-guided radiation therapy equipment comprises an installation base, a treatment couch which is fixedly arranged on the installation base and a treatment equipment main body, wherein the treatment equipment main body comprises a shield body roller, a source body roller and a collimation body roller component which are coaxially sleeved together and can rotate relative to one another, wherein the source body roller is provided with a detachable radioactive source component; the collimation body roller component is provided with a collimator; rays emitted from the radioactive source component emit into the treatment equipment main body after the beam limiting of the collimator; the treatment equipment main body surrounds the whole circumference of the treatment couch at 360 degrees; an image guide device is fixedly arranged on the source body roller and can rotate along with the source body roller, so that the image tracking of a patient in a 360-degree range and the real-time monitoring in a treatment process are realized, and a target spot follows up; and therefore, the aim of image-guided precise radioactive treatment is fulfilled.

Description

technical field [0001] The invention relates to a radiotherapy device in a medical device, in particular to an image-guided radiotherapy device. Background technique [0002] At present, the treatment equipment using gamma rays as the radiation source generally utilizes focused irradiation of gamma rays at the target point of the patient to protect normal tissues and kill lesions. With the continuous advancement of radiotherapy technology, the way of focusing rays has been developed from static focusing to rotating focusing technology. The rotating focus technology is to make the gamma ray continuously rotate around the patient's target point, so as to increase the focal-to-skin ratio and reduce the average irradiation dose received by normal tissues. There are generally two ways of rotating focusing: one is that the ray rotates along a certain central axis passing through the patient target, and the other is that the ray revolves along a certain central axis passing throug...
