Problems solved by technology

[0006] However, at this time, for example, if the irradiation dose rate of the neutron beam fluctuates for some reason after the radiation dose of the gold wire is measured, it cannot sufficiently cope with the fluctuation, and the planned irradiation dose may be adjusted. It may become difficult to irradiate the neutron beam to the object to be irradiated
That is to say, in the above-mentioned neutron capture therapy system, the neutron beam irradiation dose cannot be detected in real time, and it is also impossible to determine whether each component of the neutron capture therapy system and the detection device itself are faulty through detection.

Embodiment Construction

[0044] The application of neutron capture therapy as an effective means of treating cancer has gradually increased in recent years, among which boron neutron capture therapy is the most common, and neutrons supplying boron neutron capture therapy can be supplied by nuclear reactors or accelerators. The embodiment of the present invention takes the accelerator boron neutron capture therapy as an example, and the basic components of the accelerator boron neutron capture therapy generally include an accelerator for accelerating charged particles (such as protons, deuterons, etc.), targets and heat removal System and beam shaper, in which the accelerated charged particles interact with the metal target to generate neutrons, according to the required neutron yield and energy, the available accelerated charged particle energy and current, and the physical and chemical properties of the metal target To select the appropriate nuclear reaction, the nuclear reactions that are often discu...

Abstract

One technical scheme of the invention provides a beam diagnosis system for a neutron capture therapy system. On one hand, the accuracy of the neutron beam irradiation dose of the neutron capture therapy system is improved, and on the other hand, the beam diagnosis system is provided for being used in the neutron capture therapy system for fault diagnosis. The neutron capture therapy system comprises a charged particle beam, a neutron generating part for generating a neutron beam through a nuclear reaction with the charged particle beam through a charged particle beam inlet of the charged particle beam, a beam shaping body for adjusting the neutron beam flux and the quality generated by the neutron generating part and a beam outlet adjacent to the beam shaping body, wherein the charged particle beam inlet is accommodated in the beam shaping body; and the neutron generating part is accommodated in the beam shaping body. The beam diagnosis system comprises a charged particle beam diagnosis device and a neutron beam diagnosis device. The beam diagnosis system is used for simultaneously diagnosing whether fault happens to the neutron capture therapy system and / or the beam diagnosis system.

Description

technical field [0001] The invention relates to a beam diagnosis system, in particular to a beam diagnosis system used in a neutron capture therapy system. Background technique [0002] With the development of atomic science, radiation therapy such as cobalt 60, linear accelerator, and electron beam has become one of the main means of cancer treatment. However, traditional photon or electron therapy is limited by the physical conditions of the radiation itself. While killing tumor cells, it will also cause damage to a large number of normal tissues along the beam path; in addition, due to the different sensitivity of tumor cells to radiation, traditional radiation therapy Treatment for more radioresistant malignant tumors (eg glioblastoma multiforme, melanoma) is often less effective. [0003] In order to reduce radiation damage to normal tissues around the tumor, the concept of target therapy in chemotherapy (chemotherapy) has been applied to radiation therapy; and for tum...
