Abstract

The invention discloses a compact single-chamber proton therapy system which comprises a superconducting cyclotron system, an energy-reducing device system, a beam-flow conveying system, a scanning treating head system, a patient support system and a treatment plant; the superconducting cyclotron system generates fixed energy and proton beam flows in a certain flow intensity range, the proton energy is continuously adjustable in the range of 70-200MeV via the energy-reducing device system, the beam-flow conveying system guides the proton beam flows from the energy-reducing device system to thescanning treating head system; the scanning treatment head system is used for implementing a scanning scheme according to the treatment plan, adjusts the transverse position of the proton beam flows,and realizes the two-dimensional scanning of the beam flows. The patient support system supports, fixes and positions the patient, and cooperates with the superconducting cyclotron system, the energy-reducing device system, the beam-flow conveying system and a scanning treatment head system for realizing three-dimensional conformal and dose-modulated proton therapy. The device is good in innovation, high in practicability and compact in structure, and the construction site and cost of the proton therapy system can be reduced while the treatment effect is guaranteed.

Description

technical field [0001] The invention belongs to the field of medical radiotherapy, and relates to a single-chamber treatment system for radiotherapy using proton beams and a realization method thereof, so as to realize three-dimensional conformal intensity-modulated radiotherapy. Background technique [0002] As a representative of precision radiotherapy, proton therapy has the characteristics of superior dose distribution, outstanding biological effects, and relatively short treatment time. After protons are accelerated to 40%-60% of the speed of light, they bombard tumor lesions, release energy and dose in a concentrated manner, and form a "Bragg peak" to maximize the dose of tumor lesions and minimize the dose of surrounding normal tissues and organs to achieve treatment The effect is maximized. Proton therapy has a wide range of treatment, high cure rate and high survival rate after treatment. [0003] At present, the proton therapy system mainly relies on foreign impo...
