Abstract

The invention discloses a tumor radiotherapy system based on a proton imaging precise positioning technology. The system comprises a 240MeV superconducting cyclotron, a transport system, a vacuum system, a control system, a patient positioning system, a rotating frame, a treatment head system and a proton imaging conversion device. A proton imaging precision positioning technology is mainly realized by a pencil beam scanning treatment head and the proton imaging conversion device. In the invention, the superconducting magnet cyclotron is used to accelerate protons, proton energy can be accelerated maximumly to 240 MeV, and an energy requirement that protons pass through a human body for imaging is satisfied. Proton CT imaging is used to replace X-ray imaging so as to improve the accuracy of tumor positioning, and simultaneously, a remaining range after the protons pass through the human body is acquired, which provides a reference for the correction of a tumor treatment plan. Therefore, treatment is accurate and a whole radiotherapy effect is increased.

Description

technical field [0001] The invention relates to the application field of precision medical instruments, in particular to a tumor radiotherapy system based on proton imaging precise positioning technology. Background technique [0002] Due to the Bragg peak effect of proton energy release, proton radiotherapy has the advantages of short treatment cycle, precise killing, high cure rate and less side effects compared with traditional ray radiotherapy. [0003] In the proton radiotherapy system, there are usually two irradiation methods of proton radiotherapy: scattering type and pencil beam. Among them, the scattering type needs to pass through multi-layer deflection plates and compensators to obtain a suitable beam current. In contrast, the pencil beam method has fewer dielectric materials on the beam path, does not change the range and direction of the beam, improves the utilization rate of the beam, reduces the radiation background irradiated on the patient, and has a larger...
