Claim 5:
6. A material decomposition method of performing decomposition of a material in an object, comprising:
storing, in a memory, a plurality of correction data preliminarily generated for each combination of the three or more materials, each of a plurality of detection elements and each energy level by individually decomposing each one of three or more materials into the other respective materials of the three or more materials;
inputting radiation data of the object, which has been divided into the plurality of energy levels; and
repeatedly performing, with a processor, two-material decomposition for decomposition of the three or more materials using the radiation data at different energy levels and using the stored correction data of each detection element for each energy level to perform decomposition of the inside of the object into three or more materials.
