Abstract

The invention discloses image-guided radiation therapy equipment, which comprises a radiation therapy equipment body and a treatment table, wherein the radiation therapy equipment body further comprises a slip ring frame structure, a radiation therapy device and a computed tomography (CT) scanner; the CT scanner and the radiation therapy device are both arranged on the slip ring frame structure; the radiation therapy device comprises a ray source body; and the CT scanner comprises an X-ray tube and an X-ray detector which are arranged to be in front of and behind the ray source body by 90 degrees respectively. The image-guided radiation therapy equipment provided by the invention can realize the real-time positioning of focal points of rays and gross target volumes to realize real-time tracking, extract two-dimensional images and display in real time the variations of lesion target volumes.

Description

technical field [0001] The invention relates to radiotherapy equipment in medical instruments, more specifically, to a radiotherapy equipment under image guidance. Background technique [0002] It is well known that radiotherapy is one of the most important and basic means of tumor treatment. At present, the main equipment for tumor radiotherapy is linear accelerator, cobalt 60 treatment machine and gamma knife. But because the tumor tissue is surrounded by normal tissue, killing the tumor will damage the normal tissue at the same time. In addition, how to eliminate the influence of organs by physiological movements in radiotherapy, such as respiratory movement, bladder filling, gastrointestinal peristalsis, tumor growth and reduction, elastic deformation of organs, and positioning errors in fractionated treatments. making it impossible to locate accurately. During the treatment process, the focus of the radiation and the real-time positioning of the tumor target area cann...
