In presenting identified results of the type and/or property of substances of an object, interface functions for identification processes are enhanced without being independent of observation directions. In a data processing apparatus (12), image data are calculated based on photon counts of an X-ray beam transmitted through an object. Based on the image data, for example, every one of n-piece energy ranges (n is a positive integer of two or more) of the X-ray spectrum and every one detector pixel, attenuation information of the X-ray beam is calculated. The attenuation information includes i) inherent information inherently depending on a type or a property of the object, the inherent information being indicated by a quantity of a vector in an n-dimensional coordinate whose dimension is equal in number to the n-piece energy ranges； and ii) associated information being associated with the inherent information and depending on a length of a path along which the X-ray beam passes though the object. From the attenuation information, only the inherent information is produced which is independent of the associated information. Scattering points corresponding to the inherent information are calculated to be mapped in the n-dimensional coordinate or in a coordinate whose dimension is less than the n-dimensional coordinate.
