Problems solved by technology

If it is considered to put a photon emission detection device in the BNCT (boron neutron capture therapy) room, by making the patient take boron ( 10 B) medicine, and make the neutron beam produced by the neutron capture therapy device contain boron ( 10 B) The drug is irradiated to produce gamma rays, and then the photon emission detection device is used to detect the generated gamma rays, because in the neutron ray environment, there must be few moving parts, and fast detection is required, while the rotation of the probe in the prior art Many moving parts are required to rotate the probe, and the detection

Embodiment Construction

[0025]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. Boron Neutron Capture Therapy (BNCT) is the use of boron ( 10 B) Drugs have the characteristics of high capture cross section for thermal neutrons, by 10 B(n,α) 7 Li neutron capture and nuclear fission reaction 4 He and 7 Li two heavy charged particles, at the same time, neutrons and boron ( 10 B) Gamma rays produced after the drug reacts. refer to figure 1 and figure 2 , which show a schematic diagram of the boron neutron capture reaction and 10 B(n,α) 7 Li neutron capture nuclear reaction equation, the average energy of the two charged particles is about 2.33MeV, with high linear energy transfer (Linear Energy Transfer, LET), short range characteristics, the linear energy ...

Abstract

The present invention provides a boron neutron capture and treatment system. The system includes a neutron capture and treatment device, a photon emission detection device, and a treatment bed; afterneutrons are irradiated by a boron-containing (10B) drug, gamma rays can be generated; the photon emission detection device comprises a detection portion which surrounds the periphery of the treatmentbed and detects the gamma rays generated after the neutrons are irradiated by the boron-containing (10B) drug; the detection portion includes a first detecting portion and a second detecting portion;the first detecting portion and the second detecting portion can move away from or approach each other such that the detection portion forms a ring of which the radius can be increased or decreased;and the ring surrounds the treatment bed. According to the photon emission detection device of the boron neutron capture and treatment system of the invention, the radius of the ring of the detectionportion which surrounds an object to be irradiated can be changed according to an actual situation in boron neutron capture and treatment, and therefore, the detection accuracy of the photon emissiondetecting device can be improved.

Description

technical field [0001] One aspect of the present invention relates to the field of medical equipment, in particular to a photon emission detection device; another aspect of the present invention relates to a boron neutron capture therapy system, in particular to a boron neutron capture system with a photon emission detection device treatment system. Background technique [0002] Photon emission computed tomography is currently the most advanced equipment and imaging method in nuclear medicine. Photon emission computed tomography includes single photon emission computed tomography (Single Photon Emission Computed Tomography, referred to as SPECT, single photon emission) and positron emission computed tomography (Positron Emission Tomography, referred to as PET, positron emission). 99m Tc, 123 I, etc.) are marked on the radiopharmaceutical (the drug may be a protein or an organic molecule), the labeled drug is generally selectively absorbed by different parts of the human bo...
