Abstract

The invention provides a neutron capture therapeutic device. The neutron capture therapeutic device can conduct proper treatment in a situation that a current value generated during transmission of a charged particle beam decreases. The neutron capture therapeutic device 1 has: a first current measurement part (11) for measuring the current of a charged particle beam (P), and a second current measurement part (32) for measuring the current of a charged particle beam (P) which is closer to a downstream side than the first current measurement part (11). According to the structure, in a situation that the current value of a charged particle beam (P) occurred between the second current measurement part (32) and the first current measurement part (11) decreases, a difference is generated between a first current value and a second current value. Therefore, in a situation that the difference is larger than a threshold value, a controller (100) controls ejection of a charged particle beam (P) coming from an accelerator (10) and performs proper control corresponding to reduction of the current value of the charged particle beam (P). According to the device, proper treatment is conducted in a situation that a current value generated during transmission of a charged particle beam (P) decreases.

Description

technical field [0001] This application claims priority based on Japanese Patent Application No. 2015-071667 filed in Japan on March 31, 2015. The entire contents of this Japanese application are incorporated herein by reference. [0002] The invention relates to a neutron capture therapy device. Background technique [0003] Conventionally, a neutron capture therapy device described in Patent Document 1 is known as a neutron capture therapy device for killing cancer cells by emitting neutron beams. The neutron capture therapy device described in Patent Document 1 includes an accelerator 2 that emits a charged particle beam, and a target 5 that generates a neutron beam by irradiating the charged particle beam. This neutron capture therapy device measures the intensity (current value) of a charged particle beam emitted from the accelerator by an electron stripper 7 (stripper) installed in the accelerator.
