PROBLEM TO BE SOLVED: To provide half scanning image reconstitution algorithm corrected so as to supply satisfying image quality in addition to an advantage that a time-wise response improves compared to over-scanning image reconstitution algorithm in a fluoro-radiographic device. SOLUTION: The algorithm is provided with a process for dividing a projection data set into the prescribed number of partial sets. For the respective partial sets, two partial image are prepared. That is, one of them is the one (Ti) weighted by a first weight and the other is the one (Ui) weighted by a second weight (that is 1). A final image (Pi) is prepared from the two partial images by a formula.
