Document Type and Number:
Japanese Patent JP7430057
Kind Code:
B2
Abstract:
The present invention provides a calibration device, a therapy planning device, and a calibration method that can improve the estimation accuracy of the neutron beam amount. The solution of the invention is characterized in that a calibration device uses the measured value calculated based on the detection result of the neutron beam amount as a reference, and uses the value based on the energy distribution of the neutron beam to calibrate the estimated value related to the neutron beam amount. The calibration device uses at least one of conventional neutron fluence, conventional neutron fluence rate, predetermined number of reactions of atoms, reaction rate, Kerma absorbed dose, and rate of Kerma absorbed dose, as the value of the energy distribution of the neutron beam to calibrate the estimated value.
