Title:
A PET data processing method, a PET data processing device, a recording medium in which computer reading is possible, and a data processing method
Document Type and Number:
Japanese Patent JP6009761
Kind Code:
B2
Abstract:
A PET data processing method, a PET data processing apparatus, a computer-readable storage medium, and a data processing method which are capable of generating a uniformly sampled sinogram are provided. A method of interpolating positron emission tomography (PET) data for reconstructing a PET image, includes acquiring (201) PET event data, which was obtained by scanning an object using a PET scanner; generating (202) a two-dimensional line-of-response (LOR) sinogram from the acquired PET event data; determining (203) a plurality of triangles connecting sampling points within the LOR sinogram, wherein adjacent sampling points are connected horizontally row-by-row within the LOR sinogram to determine the plurality of triangles; and determining (208) a uniformly sampled sinogram from the LOR sinogram using the determined plurality of triangles.
