Abstract:
1. An X-ray CT apparatus, comprising an X-ray radiation source configured to radiate X-rays toward an object; an arc shaped X-ray detector including a plurality of X-ray detection segments, each of which includes a plurality of detection elements, said X-ray detector configured to detect X-rays via an X-ray path connecting a focus of the X-ray source to the X-ray detection segments; a rotation control unit configured to control rotation of the X-ray radiation source; a reconstruction unit configured to reconstruct a tomographic image based on data collected by the X-ray detector; and a fluoroscopic image creation unit configured to project data detected by the X-ray detector on a plane that crosses the X-ray path and to create a fluoroscopic image based on the projected data.
