Embodiment Construction

[0024] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition, in the following description, the same reference numerals are attached to the same or corresponding elements, and repeated descriptions are omitted. In addition, the terms "upstream" and "downstream" refer to the upstream (cyclotron side) and downstream (irradiated body side) of the emitted charged particle beam and neutron beam, respectively.

[0025] figure 1 It is a diagram showing the structure of a neutron beam irradiation system according to an embodiment of the present invention, such as figure 1 As shown, the neutron beam irradiation system 1 is an apparatus used for cancer treatment or the like by neutron beam capture therapy, and irradiates a neutron beam N to an irradiated body 34 such as a patient.

[0026] The neutron beam irradiation system 1 includes a cyclotron 10 that accelerates charged particles such as protons to gene...

Abstract

A neutron beam irradiation system that irradiates an irradiation object with a neutron beam includes: a neutron beam generating section that generates a neutron beam by being irradiated with a charged particle beam; a housing section that includes at least a moderator and that houses the neutron beam generating section; a neutron beam converging section that converges the neutron beam with which the irradiation object is irradiated; a mounting stage on which the irradiation object is mounted; and a relative movement means that relatively moves the mounting stage closer to and away from the neutron beam generating section, the housing section, and the neutron beam converging section.

Description

technical field [0001] The invention relates to a neutron beam irradiation system. Background technique [0002] As one of radiation therapy for cancer treatment and the like, there is boron neutron capture therapy (BNCT: Boron NCT) for cancer treatment by neutron beam irradiation. Conventionally, a neutron beam irradiation system (BNCT system) for performing this boron neutron capture therapy has been developed. The neutron beam is generated by the particle beam; the neutron beam convergence part converges the irradiated neutron beam; and the mounting table mounts the irradiated body such as a patient. In the neutron beam irradiation system described in this patent document 1, the neutron beam generated in the neutron beam generation part is intended to irradiate the object to be irradiated on the mounting table through the neutron beam convergence part. In addition, in this neutron beam irradiation system, the neutron beam generation part is accommodated by the accommoda...
