<p><P>PROBLEM TO BE SOLVED: To improve the quality of a reconstructed image by using Gaussian-based expansion data generated by a Gaussian-based expansion data generating part. <P>SOLUTION: When a group of (preprocessed) projection data is stored in a projection data storage section 35 in an image reconstructing apparatus, the Gaussian-based expansion data generating section 36b generates a group of Gaussian-based expansion data expanded from each projection data group through linear combination based on a plurality of Gaussian functions that are stored by a Gaussian function storage section 36a and have different center points. A reconstructed image generation section 36c generates a reconstructed image using the Gaussian-based expansion data generated by the Gaussian-based expansion data generating section 36b, and stores the generated reconstructed image in an image storage section 37. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
