PROBLEM TO BE SOLVED: To improve the accuracy of an image analysis by providing an operator with a new image which is reduced in both an artifact and noise, in X-ray CT equipment.SOLUTION: X-ray CT equipment 1 comprises an X-ray tube, a high-voltage power supply, an X-ray detector, and a processor. The processor reconstructs a unicolor X-ray image or a multicolor X-ray image imaged at a first X-ray energy band as a first image on the basis of pre-construction data which are obtained by scanning an analyte, reconstructs a multicolor X-ray image imaged at a second X-ray energy band which is wider than the first X-ray energy band as a second image on the basis of the re-construction data which are obtained by scanning the analyte, specifies a region of a correction object on the first image as a correction region, and corrects the correction region out of the second image on the basis of the first image.SELECTED DRAWING: Figure 1 |
