Proton therapy system based on compact superconducting cyclotron

Abstract

The invention discloses a proton therapy system based on a compact superconducting cyclotron. The proton therapy system includes a superconducting cyclotron system, an energy selection system and a beam transportation system, a fixed treatment room subsystem and a rotary frame treatment subsystem; the fixed energy proton beam led out by the superconducting cyclotron in the superconducting cyclotron system can be a continuously adjusting proton beam of 70-200MeV via the energy selection system, so that the longitudinal adjustment of the range during the proton therapy of tumors can be met; thebeam is transmitted to the fixed treatment room subsystem and the rotary frame treatment subsystem via the beam transportation system; the superconducting cyclotron system, the energy selection system, the beam transportation system and a treatment head are subjected to cooperative control to realize the transverse expansion of the proton beam, so that the intensity modulation treatment of the tumor can be completed. According to the invention, the innovation is good, the practicability is high, the beam intensity of the superconducting cyclotron is adjustable, and the intensity modulation treatment can be realized; and the system has an extremely important promotion effect on the accuracy, effectiveness and high efficiency of tumor treatment of a patient.

Description

technical field

[0001] The invention belongs to the field of medical equipment, in particular to a proton therapy system based on a compact superconducting cyclotron. Background technique

[0002] With the current rising demand for cancer treatment, proton therapy has become an effective means of treating tumors. Proton therapy has a unique "Bragg peak" biological effect, the dose loss on the way to the target area is very small, protons can release most of their energy at a predetermined depth in the body, forming a "Bragg peak" The precise energy release trajectory can precisely treat the tumor area and effectively kill the lesion. At the same time, the purpose of reducing the damage to surrounding healthy tissues is to greatly reduce the damage to normal cells, improve the comfort of patients during treatment, and improve the quality of life of patients after surgery. Compared with ordinary radiotherapy technology, proton therapy has a wide range of treatment, high cure...
