PROBLEM TO BE SOLVED: To provide an X-ray CT device compensating properly X-ray intensity from initial view, and providing satisfactory image quality, even when reference channels in both sides of an X-ray detector are covered by a specimen or the like. SOLUTION: This X-ray CT device 1 holds outputs in respective views of the reference channels RefL, RefR provided in both ends of the X-ray detector 205, as reference data, when acquiring an air calibration data performed with no specimen before actual scanning. The X-ray CT device 1 determines, in every view, whether the reference channel is covered with the specimen or not, when radiographing the specimen, calculates a pseudo-reference data about the view, when covered, and corrects a reference, using the pseudo-reference data. The pseudo-reference data are calculated based on the reference data as to the view corresponding to the view. COPYRIGHT: (C)2011,JPO&INPIT
