Summary:PROBLEM TO BE SOLVED: To acquire the distribution of the scattered radiation of radiation generated by the influence of a subject and to perform the correction of reducing the influence of the scattered radiation from reconstructed images. SOLUTION: Information on a scattered radiation distribution is acquired at each rotation angle preliminarily determined by a rotation means on the basis of images obtained from a first radiation detection sensor having no grid and a second radiation detection sensor having a grid. The image obtained from the second radiation detection sensor is corrected based on the information on the scattered radiation distribution so as to reduce the influence of the scattered radiation. On the basis of the corrected image, reconstruction processing is performed. COPYRIGHT: (C)2010,JPO&INPIT
