ABSTRACT:
In a gamma camera comprising a hollow-body scintillator crystal which is open at one end and has optoelectronic transducers disposed at its outer surface for sensing light signals generated by gamma radiation entering the scintillator crystal, a collimator with a pin hole is disposed at the open end of the scintillator crystal and has a cone-like projection with an apex where the pin hole is disposed. A number of such hollow scintillator crystals may be arranged on sheets with cone-like projections having pin hole apexes so as to be coaxial with the pin holes.
