Problems solved by technology

The advantage of this scheme is that it can use MR image-guided radiotherapy to treat accurately at the same time. The disadvantage is that the strong magnetic field of MR will change the trajectory of the radiotherapy electron beam and interfere with the trajectory of X-rays, so it is difficult to accurately control the X-rays. therapeutic dose

Abstract

The invention discloses a radiation treatment device which includes: a radiation treatment part used for supporting and moving a sickbed of a patient; and an MR monitoring part which is arranged on the horizontal movement direction of the sickbed. The radiation treatment device scans a patient in treatment in a real-time manner through the MR monitoring part and adjusts a treatment scheme according to the scanning result so that the precision and speed of radiation treatment are effectively improved and damages on healthy tissues of the patient are reduced as far as possible while it is ensured that radiation of enough dose radiates a tumor area.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a radiotherapy equipment with MR monitoring function. Background technique [0002] Radiation therapy equipment refers to equipment that uses high-energy electromagnetic radiation (X radiation, gamma radiation) or particle radiation (electrons, protons, carbon ions) to destroy diseased tissues, and is widely used in cancer treatment in medicine. In radiation centers of radiation therapy facilities where high radiation doses are produced in a targeted manner, the radiation target often changes in the body during the radiation process. If the tumor has grown or shrunk in the time between planned radiation and actual radiation. And in the process of treatment, according to the progress of radiation, the center of the lesion area changes. For this reason, it has been proposed to monitor the position of the radiation target in the body by imaging equipment during the radiation proce...
