Technical Field

The invention relates to the technical field of proton treatment, in particular to a device and a method for remotely measuring residual dose in a proton treatment system.

Background

Proton therapy is a novel radiotherapy technology with wide application prospect and obvious curative effect on various cancers, and the research and development of a proton therapy system is still hot at present in China. The proton as positively charged particle enters into human body at extremely high speed, because of its high speed, the probability of action with normal tissue or cell in vivo is low, when reaching the specific part of cancer cell, the speed is gradually reduced and stopped, the maximum energy is released, the Bragg peak (Bolat peak) is generated to kill cancer cell, and at the same time, normal cell tissue is effectively protected. The proton therapy has the characteristics of strong penetrating performance, good dose distribution, high local dose, less side scattering, small penumbra and the like, and particularly shows great superiority for treating tumors with important tissue and organ wrapping. The proton therapy has wide adaptation diseases and has better curative effects on benign and malignant brain tumor, spinal cord tumor, cerebrovascular disease, head and neck tumor, eye lesion, chest and abdomen tumor, pediatric tumor, other diseases and the like. The clinical treatment data in foreign countries show that the effective rate of the proton therapy on the tumor reaches more than 95%, the five-year survival rate reaches up to 80%, and the treatment method which is evaluated by the high-energy physical and medical fields has the best curative effect and the least side effect is adopted.

Proton therapy treatment facilities typically consist of a single proton cyclotron and multiple treatment rooms, the cyclotron generating a particle beam that is then selectively directed to one of the various treatment rooms. The proton cyclotron for accelerating negative hydrogen ions ionizes hydrogen to make the hydrogen become negative hydrogen ions with negative electricity, the negative hydrogen ions are accelerated in the cyclotron continuously, when the required energy is reached, two electrons carried by the negative hydrogen ions are stripped by a stripping film to make the negative hydrogen ions become protons, thereby realizing the extraction of proton beams. The proton beam is transported in the vacuum beam pipeline and is transported to each treatment bin through the beam line. Usually, the proton beam generated by the proton cyclotron has a fixed energy, for example, the proton beam generated by the proton cyclotron is a proton treatment-dedicated cyclotron under development by the same applicant as the national institute of atomic energy science, and the proton energy generated by the cyclotron is 230 MeV. The proton beam with the energy of 230MeV has the range of 32cm in human tissues, but the distribution of the tumor in the human body cannot be all at the depth, so the energy of the proton needs to be adjusted according to the depth of the tumor. The energy selection system is an important component of proton therapy, wherein the degrader can achieve the proton energy reduction from the initial 230MeV to any energy point within the interval of 70 MeV. This is accompanied by a high residual dose rate of the energy selection system. In addition, the transportation of the proton beam in the beam line is restrained by various devices such as magnets, collimators, diaphragms and the like, so that loss is inevitably generated, and the lost protons cause severe activation of parts such as the beam line, the Faraday cage and the magnets and generate high residual dose.

Usually, the proton treatment system is designed by selecting some materials with smaller residual dose to design the components such as the energy degrader, the beam streamline, the faraday cage, the slit and the like with larger possible loss of protons, but this is also relative, and a higher residual dose is inevitably generated during the operation of the proton treatment system. With properly chosen materials, the residual dose generated upon proton loss can be greatly reduced over a period of days to tens of days, with the best method of reducing the residual dose upon shutdown for cooling being common. However, due to the particularity of the proton treatment system, the proton treatment system cannot be stopped for a long time to wait for cooling due to cost problems, patient conditions and other factors, which is a great challenge for operation and maintenance personnel, and the operation and maintenance personnel may need to enter some areas with high residual dose to operate when the accelerator fails.

Measurements are typically taken by telescoping long rod detectors to minimize gamma exposure to personnel when entering areas of higher dose. However, long rod detectors have a limited length and in many cases personnel have to approach the high dose area to make the measurement. Meanwhile, due to the fact that the energy selection system, the transportation line, the beam collector and other components are complex in design structure and compact in space structure, certain personnel may stay for a certain time during measurement, and operation and maintenance personnel can absorb high radiation dose.
