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.

Measuring device, measuring method, measuring system, and radiation therapy system

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.

Neutron capture therapy system and therapy planning system for neutron capture therapy

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.
