摘要 |
The purpose of the present invention is to reduce statistical errors in material decomposition images. In order to achieve this purpose, the present invention is characterized by having: a scatter plot generation unit (414) that generates a scatter plot in which the axes represent the concentrations of base materials used in base material decomposition and pixels of a material decomposition image output as a result of the base material decomposition are plotted against the corresponding concentrations of the base materials of the base material decomposition; an angle processing unit (415) that rotates the scatter plot to minimize the statistical errors of plot points plotted thereon; and a pixel conversion unit (416) that converts the pixels of the material decomposition image on the basis of the pixels in the scatter plot where the statistical errors are minimized by the error minimization unit. |
