摘要
To provide an analysis device for an energy decomposition CT with which the response function of a detector is calculated appropriately, and the energy distribution of the transmission X-ray for an unknown object can be obtained with high accuracy using this response function.SOLUTION: An analyzer 20 of the energy decomposition CT includes an acquiring unit 131 that acquires a measurement value acquired by measuring the measured value with a detector 12 that detects the X-ray as X-rays having a plurality of X-ray energy spectra different from each other that have been emitted from an X-ray source 11 and passed through the specimen, a derivation unit 133 that derives an energy distribution of the transmitted X-rays from the measured value using a response function indicating the relationship between the energy of the X-ray incident on the detector 12 and the energy applied to the detector 12, and an arithmetic unit 132 that calculates the response function by adding the X-ray scattering element.SELECTED DRAWING: Figure 2
