Trapezoidal back projection for positron emission tomography reconstruction

Trapezoidal back projection for positron emission tomography reconstruction

Abstract Background In the back projection step of the 3D PET reconstruction, all Lines of Responses (LORs) that go through a given voxel need to be identified and included in an integral. The standard Monte Carlo solution to this task samples stochastically the surfaces of the detector crystals and...
