Abstract
An X-ray detector (), configured to have X-ray detecting elements () arranged in array, detects the intensity of X-rays that are radiated from the X-ray tube () and have passed through a subject (). A data processing device () executes steps of: arranging scan data, which is based on the intensity of X-rays, in an array sequence of the X-ray detecting elements () or in a time sequence, to detect an anomalous scan data; associating a weight greater than '1' with scan data adjacent to the anomalous scan data, and associating a weight of '1' with other imaging data; calculating an update amount of a pixel vector that reflects these weights; and performing an iterative operation using the update amount to generate an X-ray CT image of the subject ().
