Abstract

The invention discloses a full-circumference spherical surface stereotactic radiotherapy device. The device comprises an X-band accelerator, a multi-leaf collimator, a treatment couch, an image system, an EPID, a fixed rack and a rotary rack, the rotary rack is arranged on the fixed rack in a rotatable mode, the treatment couch is fixed relative to the fixed rack, the image system is arranged on the rotary rack, the X-band accelerator is connected to the multi-leaf collimator, and the X-band accelerator is arranged on the rotary rack, so that the X-band accelerator forms spherical irradiationon a treatment center; and the EPID is arranged on the rotary rack, and the EPID is orthogonal to a beam of the X-band accelerator so as to receive residual beams. The full-circumference spherical surface stereotactic radiotherapy device can perform full-circumference spherical surface stereotactic radiotherapy on a patient.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a full-circumferential spherical stereotactic radiotherapy device. Background technique [0002] As we all know, stereotactic radiation therapy began in the 1950s. The Swedish neurosurgery expert Lars Leksell first proposed "radiotherapy". Effect. This single high-dose precise irradiation technique is called "stereotactic radiosurgery (SRS)". [0003] Since the 1980s, medical accelerators have used isocenter non-coplanar multi-arc rotation to realize X-ray SRS treatment, and the scope of application has gradually expanded from the treatment of benign intracranial lesions to the treatment of intracranial malignant tumors. [0004] With the promotion and application of SRS around the world, some radiotherapy centers began to use less fractionated hyperfractionated dose irradiation mode, which was defined as "stereotactic radiation therapy (SRT)". In the early 1990s, SR...
