<P>PROBLEM TO BE SOLVED: To provide a PET data processing method with which a uniformly sampled sinogram can be generated at high speed, PET data processing apparatus, computer readable recording medium and data processing method. <P>SOLUTION: A method of interpolating PET data for reconfiguring a PET image includes steps of collecting PET event data obtained by scanning a specimen using a PET scanner, generating a two-dimensional LOR sinogram from the collected PET event data, determining a plurality of triangles connecting sampling points in the LOR sinograms, in which adjacent sampling points in the LOR sinograms are connected for each column in a horizontal direction in order to determine the plurality of triangles, and determining a uniformly sampled sinogram from the LOR sinograms using the plurality of determined triangles. <P>COPYRIGHT: (C)2012,JPO&INPIT |
