Sinogram Blurring Matrix Estimation from Point Sources Measurements with Rank-One Approximation for Fully 3D PET
An accurate system matrix is essential in PET for reconstructing high quality images. To reduce storage size and image reconstruction time, we factor the system matrix into a product of a geometry projection matrix and a sinogram blurring matrix. The geometric projection matrix is computed analytica...
