Cancer radiation therapy image guiding equipment

Abstract

The invention discloses cancer radiation therapy image guiding equipment. The cancer radiation therapy image guiding equipment includes an annular rack, a therapeutic head and a plurality of X-ray imaging systems, wherein the therapeutic head and the X-ray imaging systems are mounted on the outer circumferential side face of the annular rack; and an EPID image collection system panel receiver anda plurality of X-ray panel receivers are mounted on the inner circumferential side face of the annular rack, wherein the EPID image collection system panel receiver and the therapeutic head are oppositely arranged at the two sides of the annular rack respectively, the EPID image collection system panel receiver is used for receiving rays emitted by the therapeutic head, the X-ray panel receivers and the corresponding X-ray imaging systems are oppositely arranged at the two sides of the annular rack respectively, and the X-ray panel receivers are used for receiving rays emitted by the X-ray imaging systems. According to the cancer radiation therapy image guiding equipment, EPID image collection imaging and the X-ray imaging systems are integrated, 2D / 2D image guiding and 3DCBCT image guiding are finished rapidly, real-time image guiding and dose guiding are achieved, image quality and collection time are both taken into account, clinical therapeutic efficiency is improved, a combined therapy of the cancer radiation therapy image guiding equipment and an after-loading therapy machine is achieved, and meanwhile, internal irradiation and external irradiation are conducted synchronouslyor independently.

Description

technical field [0001] The invention relates to the field of tumor treatment equipment, in particular to an image guidance equipment for tumor radiotherapy. Background technique [0002] Tumor radiotherapy equipment treats tumors with high-energy rays, which has the advantages of high efficiency and precision. The main component of tumor radiotherapy equipment is a ray accelerator treatment head, which accelerates electrons through the accelerator to output high-energy rays, and irradiates the tumor for treatment. [0003] At the same time, image-guided radiation therapy is also needed, which is to use various imaging equipment to monitor tumors and normal organs before and during treatment, and adjust the treatment position and treatment conditions according to the changes in tumor and organ positions, so that the irradiation field is tight. Tightly "follow" the target area. Clinically, we are very concerned about the real-time position of the tumor under treatment. Using ...

Problems solved by technology

Clinically, we are very concerned about the real-time position of the tumor under treatment. Using the EPID image acquisition system, the ray source is the same as the treatment beam, but the spatial resolution of the image is low, and image monitoring can only be performed in the 2D direction; single X-ray Compared with the EPID image acquisition system, the image quality of the imaging system is improved outside the focus, and it can complete 2D / 2D and 3DCBCT image guidance, but its 2D / 2D method requires at least two positions of image acquisition for spatial positioning, and the selection of positions and shooting are both It takes a little more time, and 3DCBCT needs to choose more gantry angles, so the traditional mode cannot complete the fusion treatment
