Claim:
1. A single stationary detector head for three dimensional positron emission tomography imaging or single photon emission tomography from a stationary position comprising: a photomultiplier tube or silicon photomultiplier; a plurality of groups of scintillation crystal slices, each group of scintillation crystal slices comprising a plurality of scintillation crystal slices, mounted on the photomultiplier tube or silicon photomultiplier; and a plurality of shielding material slices mounted on the photomultiplier tube or silicon photomultiplier having a height greater than a height of the crystal slices, the shielding material slices each alternating with each group of scintillation crystal slices in a repeating pattern, beginning and ending with the shielding material slice, wherein the shielding material slices generate a plurality of shadows detected by the scintillation crystal slices based on a location of a source of activity emitting gamma particles toward the detector head within a field of view.
