An advanced fully 3D OSEM reconstruction for positron emission tomography

A fully 3D OSEM reconstruction method for positron emission tomography(PET) based on symmetries and sparse matrix technique is described.Great savings in both storage space and computation time were achieved by exploiting the symmetries of scanner and sparseness of the system matrix.More reduction o...
