A gamma camera comprising:
a plurality of pixelated detectors wherein each pixelated detector provides a detector signal responsive to photons that are incident on it;
a plurality of processing circuits that receive said detector signals and provide processed signals responsive to said detector signals; and
at least one printed circuit board on which said processing circuits are mounted and having conductors thereon that carry said detector signals to said processing circuits;
wherein said processing circuits are mounted on said printed circuit board at locations remote from said detectors; and
wherein said plurality of pixelated detectors form a two-dimensional planar array.
