PROBLEM TO BE SOLVED: To provide a method for switching a vector for offset correction capable of shortening processing time relating to the offset correction, and an X-ray CT device. SOLUTION: In the case that the vector for the offset correction of the previous time can be diverted, the vector for the offset correction of the previous time is diverted and the vector for the offset correction is not newly calculated. In the case of changing image reconstitution software and in the case of interrupting the image reconstitution of the previous time, the vector for the offset correction is calculated again and data to be the object of the image reconstitution of this time are offset-corrected by using the vector for the offset correction. Thus, the processing time relating to the offset correction is shortened. Safety in the case of changing the image reconstitution software and in the case of interrupting the image reconstitution of the previous time is secured. COPYRIGHT: (C)2004,JPO
