Abstract: A measuring device includes an ionization chamber where air is contained and a measurement value relating to radiation including a neutron ray and a gamma ray is measured, a detector that detects a detection value relating to the neutron ray, and a controller that calculates a dose of the gamma ray based on the measurement value measured in the ionization chamber and the detection value detected by the detector.

Abstract: A neutron capture therapy system includes a therapy table on which an irradiation target is placed, a neutron beam irradiation unit which irradiates the irradiation target placed on the therapy table with a neutron beam, a position measurement unit which measures a position of the irradiation target placed on the therapy table, and a radiation dose distribution output unit which outputs a radiation dose distribution of a neutron beam used for irradiating the irradiation target, based on an amount of positional misalignment of the position of the irradiation target measured by the position measurement unit.

Abstract: A neutron capture therapy system that irradiates an object to be irradiated with a neutron beam by using an irradiation device, and includes a treatment planning device, a control device, and the irradiation device included in a network via which transmission and reception of information are possible, in which the treatment planning device creates treatment plan information related to a treatment plan and transmits the treatment plan information to the control device, in which the control device adjusts the treatment plan information transmitted from the treatment planning device to be usable in the irradiation device, and in which the irradiation device irradiates the object to be irradiated with the neutron beam on the basis of the treatment plan information adjusted by the control device.

Abstract: Provided is a therapy planning system for neutron capture therapy performing therapy planning thereof irradiating an irradiation target with a neutron beam. The system includes an image acquiring unit acquiring an image of the irradiation target; a body outline setting unit setting a body outline of the irradiation target based on the image acquired by the image acquiring unit; a vacancy region setting unit setting a part where a value of a pixel of the image is within a range set in advance on an inner side of the body outline set by the body outline setting unit, as a vacancy region including a vacancy; and a mucosa region setting unit setting apart on an outer side by a first thickness from a surface of the vacancy region set by the vacancy region setting unit on the inner side of the body outline, as a mucosa region including mucosa.

Abstract: A neutron capture therapy system includes a neutron beam irradiation unit that applies neutron beams, a treatment table on which an irradiation object irradiated with the neutron beams is mounted, a storage unit that stores distribution data indicating a distribution of hydrogen atoms or nitrogen atoms of a part to be irradiated of the irradiation object, a gamma ray detection unit that detects gamma rays generated from the irradiation object due to irradiation with the neutron beams, and a neutron flux distribution calculation unit that calculates a distribution of neutron flux in the irradiation object on the basis of the distribution data stored in the storage unit and gamma ray distribution data detected by the gamma ray detection unit.
