PURPOSE:To provide the artifact correction system for correcting the low-count artifacts generated in the images of patient's shoulder and waist in continuous diagnosis images and its X-ray CT device. CONSTITUTION:The interpolating projection data in an arbitrary slice position is determined by interpolation processing in accordance with the projection data obtd. in a detecting section and the position data in a bodily axis direction. A data correction section 8 for correcting the projection data relating to the specific position of the patient at the time of reconstituting the image has a projection data storage section 8A storing the projection data obtd. from a data collecting section 7, a correction parameter input section having the previously obtd. section data and angle data indicating the range of the specific section, a correction table forming section 8D for forming a weight coefft. and a projection data correction section 8E for correcting the projection data of the data collecting section 7. |
