PROBLEM TO BE SOLVED: To provide a method for reconstructing tilted cone beam data acquired by using a CT (computed tomography) apparatus. SOLUTION: The CT apparatus (10) has a gantry (24) and a table (39). The gantry (10) has an x-ray source (12) and a detector array (20) with columns and rows. The gantry (24) is tilted at a gantry tilt angle with respect to the table (39) and a plurality of projection data are acquired by using the CT apparatus (10). Fan-parallel rebinning is performed on a row by row basis to form a plurality of reconstructed pixels. The coordinate locations of the plurality of reconstructed pixels are adjusted based on the gantry tilt angle and used to form a reconstructed image. COPYRIGHT: (C)2006,JPO&NCIPI
