CALIBRATION APPARATUS, CALIBRATION METHOD, AND CALIBRATION PROGRAM

原文（中国語）

Calibration data of a photon counting detector consisting of a plurality of detection elements that output detection signals corresponding to photon energies of incident radiation is acquired. A processor is configured to: acquire a plurality of detection signals output from the plurality of detection elements of the photon counting detector in accordance with a predetermined acquisition condition; derive a difference signal representing a difference between at least one representative detection signal that is representative of the plurality of detection signals and the plurality of detection signals; and store the at least one representative detection signal and the difference signal, as calibration data in accordance with the acquisition condition.
