Claim:
1. An X-ray CT apparatus comprising: an X-ray source for irradiating an X-ray to an object from the surroundings; an X-ray detector for detecting an X-ray transmitted through the object; an image processing device for generating projection data from the detected information about the transmitted X-ray and reconstructing a tomographic image of the object based on the projection data; and a display device for displaying the tomographic image, wherein the image processing device comprises: a motion direction obtaining unit for obtaining a motion direction of a site to be scanned; a reconstruction data range calculation unit for calculating a reconstruction data range that is a range of projection data to be used for reconstruction based on the motion direction; and an image reconstruction unit for reconstructing an image using the projection data of the calculated reconstruction data range.
