Abstract
Scattered radiation is estimated by using a reduced image generated from a projection image, and the scattered radiation image of the projection image is acquired by enlargement processing. The scattered radiation correction of the projection image is executed by subtracting the obtained scattered radiation image from the projection image. In addition, when a primary X-ray image and a scattered radiation image in each projection direction are to be obtained by sequential approximation calculation, a primary X-ray image which has already been identified in an adjacent projection direction is used as a first estimated value (initially set value) in next sequential calculation.
