Abstract
According to an embodiment, an apparatus includes a reference calculator, a peak calculator, a coefficient calculator, and a calibrator. The reference calculator is configured to calculate, as a first value, a most frequent electrical signal level from a first set of electrical signal levels output from the respective pixels of a detector for radiation. The peak calculator is configured to calculate, as a second value, a peak level of radiation energy of a characteristic X-ray, based on a relation between energy and intensity of radiation obtained from the first set. The coefficient calculator is configured to calculate a coefficient by dividing a difference between the first and second values by the peak level. The calibrator is configured to multiply an electrical signal level of each pixel by the coefficient and add the first value to the multiplication to calibrate a relation between detection output and incident radiation of the detector.
