| titleOfInvention | Crest frequency distribution acquisition apparatus, crest frequency distribution acquisition method, crest frequency distribution acquisition program, and radiation imaging apparatus |
| abstract | The object of the present invention is to reduce the cost of a radiation imaging apparatus to which a detector for generating a high-accuracy wave frequency distribution in a short time and applying a calibration using the wave frequency distribution is applied. Acquisition of pulse frequency distribution of a radiation detector provided with a plurality of counting units for counting the detection signal and outputting the count value when the value of a detection signal for detecting incident X-rays is equal to or greater than a threshold value The apparatus sets a first threshold value V1 for the first counting unit and sets a second threshold value V2 higher than the first threshold value V1 for the second counting unit. A threshold value setting unit that resets a first threshold value V1 ′ different from the first threshold value V1, a measurement control unit that performs a plurality of measurements, and a plurality of measurements performed according to the measurement control unit A crest frequency distribution generating unit that generates a crest frequency distribution for the first threshold in the first counting unit based on the difference between the count values of the first counting unit and the second counting unit obtained by A crest frequency distribution acquisition device is provided.
