Fully superconducting proton therapy system

Abstract

The invention discloses a full superconducting proton therapy system comprising a superconducting cyclotron, wherein the superconducting cyclotron is used for generating proton beam; A superconduct rotary treatment chamber is arrange beside that superconducting cyclotron; The superconducting rotary treatment chamber includes a beam line of the rotary treatment chamber. The above technical scheme is adopt, The proton therapy system, using the mode of superconducting cyclotron equipped with superconducting rotating treatment chamber, As that system is compact in layout and small in occupy space,the weight of the equipment is greatly reduced, thereby further reduce the manufacturing cost, namely, the invention provides a scheme of a fully superconducting proton therapy system for reducing the size, weight and the manufacturing cost of the proton therapy equipment.

Description

technical field [0001] The invention relates to the technical field of proton therapy and also belongs to the technical field of biology (medical treatment), in particular to a full superconducting proton therapy system. Background technique [0002] At present, the incidence of cancer in our country is getting higher and higher, and it has become one of the biggest killers that endanger the health of our people. The usual treatment methods include surgery, gamma knife, proton / heavy ion therapy, etc. [0003] The proton / heavy ion therapy mainly uses the accelerator to generate a proton / heavy ion beam with a certain energy, and transmits the beam to the target area through various electromagnetic components to bombard the tumor cells to achieve the therapeutic effect. Because protons have sharp Bragg peaks in substances, that is, their energy will be lost to the cancerous position to the greatest extent, so it can kill cancerous cells while protecting normal tissues to the gr...

AI Technical Summary

Problems solved by technology

Since the current superconducting magnets cannot achieve the rapid magnetic field changes like normal temperature magnets, either the scanning speed of the superconducting rotating therapy cabin (NIRS-HIMAC) is slow, or the achromatic bending section design is adopted to increase the The momentum acceptance of the superconducting rotating treatment cabin makes protons within the range of 0-30cm of the human body. When changing the scanning depth, only a certain working point of the superconducting magnet excitation current needs to be set, and each working point can cover nearby protons. There is no need to adjust the excitation current of the superconducting magnet; only after the range exceeds the coverage of each operating point, adjust the excitation current of the superconducting magnet to the next operating point.

The latter method is well conceived, but on the one hand, no matter how optimized the momentum acceptance under a fixed magnetic field is, there is a limit; The scanning speed of the superconducting rotating treatment cabin still cannot exceed the design of the PSI room temperature rotating treatment cabin
