Abstract
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.
