PROBLEM TO BE SOLVED: To provide a high-quality tomographic image by half reconstruction.;SOLUTION: In this apparatus, each view channel data of the same channel number i is multiplied by a weighting coefficient having a nearly trapezoidal profile over a plurality of views in an angle range wherein an angle corresponding to a fan angle of a fan beam X-rays is added to 180 degrees, and the tomographic image is reconstructed by use of the view channel data multiplied by the weighting coefficint.;COPYRIGHT: (C)2002,JPO
