ABSTRACT:
An X-ray computerized tomographic (CT) imaging apparatus which can achieve a multiple energy scanning system on a real time basis so that plural kinds of tomographic information can be obtained corresponding to plural types of energy characteristics. The X-ray CT imaging apparatus includes: an X-ray tube for irradiating an X-ray to a biological body under medical examination; a plurality of detection systems for detecting an X-ray energy transmitted through the biological body, in which the plural detection systems have different energy characteristics respectively; a data acquisition unit for acquiring respective transmission X-ray energy data of the biological body which are detected by the plural detection systems; and a reconstruction unit for reconstructing a tomographic image for the biological body in accordance with data from the data acquisition unit.
