Embodiment Construction

[0024] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition, the same code|symbol is attached|subjected to the same part or a corresponding part in each drawing, and repeated description is abbreviate|omitted.

[0025] figure 1 and figure 2 The shown neutron capture therapy device 1 is a device for cancer treatment using boron neutron capture therapy. In the neutron capture therapy device 1, for example, for injection containing boron ( 10 The neutron beam N is irradiated to the tumor of the patient (irradiated body) M with the medicine of B).

[0026] The neutron capture therapy device 1 includes an accelerator 2 , a beam transmission device 3 , a neutron beam irradiation unit 4 , and a boron injection unit 17 . The accelerator 2 is, for example, a cyclotron. The accelerator 2 accelerates charged particles such as hydrogen ions to produce a proton beam (proton beam) as a charged particle beam...

Abstract

The invention provides a neutron capture therapy device which is capable of improving reliability of a boron neutron capture therapy. The neutron capture therapy device (1) in the invention is radiates neutron beams onto a object to be radiated (M), and boron in the radiated object (M) is enabled to react with the neutrons. The neutron capture therapy device (1) has a neutron beam radiating part (4) used for radiating the neutron beams (N) onto the object to be radiated (M) and a boron concentration measuring part (32) used for measuring in real time the concentration of boron in the object to be radiated (M) when the neutron beam radiating part (4) radiates the neutron beams (N).

Description

technical field [0001] This application claims priority based on Japanese Patent Application No. 2015-043840 filed in Japan on March 5, 2015. The entire content of this Japanese application is incorporated in this application by reference. [0002] The invention relates to a neutron capture therapy device. Background technique [0003] As one type of radiation therapy in cancer treatment and the like, there is boron neutron capture therapy (BNCT; Boron Neutron Capture Therapy) for cancer treatment by irradiation of neutron beams. In boron neutron capture therapy, boron is absorbed into cancer cells and neutron beams are irradiated to the affected area, and boron and neutrons react in cancer cells to destroy cancer cells. [0004] The neutron capture therapy apparatus for performing this boron neutron capture therapy includes: a charged particle beam generating unit that generates a charged particle beam; and a neutron beam generating unit that generates a neutron beam by i...
