A voxel-driven system matrix design for multipinhole SPECT with overlapping projection

Single pinhole SPECT can provide high-resolution functional imaging of small animals, while multipinhole SPECT can further increase photon sampling and hence improve system sensitivity. In addition, overlapping projection of a multipinhole system can improve the overall usage of detector area, but s...
