Abstract:
1. A radiography apparatus for producing a time-sequentially continuous plurality of images of a subject using projection data items of the subject obtained by performing a single main scan by which a radiation irradiated to the subject and transmitted through the subject is detected, said radiographic apparatus comprising: a conditions-for-main scan designation device for designating the conditions for the single main scan that is staffed after a contrast medium is injected into a blood vessel of the subject, the single main scan producing the time-sequentially continuous plurality of images at one position; a radiation tube for irradiating radiation to the subject during the single main scan according to the conditions designated by said conditions-for-main scan designation device; a detection device for detecting radiation irradiated from said radiation tube and transmitted through the subject, said detection device comprising a plurality of detection elements arranged in an array form; and an image reconstruction device for reconstructing the time-sequentially continuous plurality of images of the subject from the projection data items of the single main scan, said image reconstruction device configured to reconstruct a first image of the time-sequentially continuous plurality of images with respect to a blood flow of the subject based on time-sequential information and a second image of the time-sequentially continuous plurality of images with respect to the blood vessel of the subject using the projection data items obtained during the single main scan.
