PURPOSE:To shorten a time for reconstruction and to increase resolution by subjecting data processed preliminarily to a centering processing and then to a bundle average processing. CONSTITUTION:Data detected by a detector 25 are subjected to a preliminary processing comprising offset correction, LOG conversion, REF correction, AIR correction, etc. in a preliminary processing device 3 of a reconstructing device 1, and then a center-aligning processing is applied thereto in a center-aligning device 5. Next, in a centering device 7, the data are rearranged so that the data on an X-ray path passing through the center of reconstruction be in the center of traverse. Then, bundle-average processing is executed in a bundle- average processing device 9, and further processings by a convolution device 11 and a back projection device 13 are executed. An image thus reconstructed is displayed in a display device 15. |
