ABSTRACT:
An X-ray CT apparatus enables decreasing the degradation of image quality and reducing futile exposure to X-ray in a helical shuttle scan. The X-ray CT apparatus comprises: a gantry rotating device having an X-ray generator for generating the X-ray and an X-ray detector for detecting the generated X-ray and transmitted through a subject; a gantry controller for performing the helical shuttle scan by reciprocally moving the gantry rotating device and the cradle; a scan condition setting device for setting the scan condition of the helical shuttle scan in a predetermined range in the direction of body axis of the subject; an X-ray projection data acquisition device for acquiring the X-ray projection data; a scan controller for controlling the scan as specified in the scan condition; and a image reconstruction device for performing the image reconstruction processing based on the X-ray projection data.
