1. A nuclear imaging system, comprising:

  • a. a radiation guide structure comprising one of a collimator or pinhole, andb. an imaging detector positioned proximate the radiation guide structure, comprising;

    (1) a plurality of detection modules, each having an exposure surface a surface opposite the exposure surface, and a plurality of sides, the exposure surface being substantially covered with radiation detecting material wherein each detection module is buttable on all sides with adjacent detection modules such that the imaging detector has substantially no dead regions between butted detection modules, and wherein each detection module further includes a plurality of semiconductor detection elements for producing electrical pulses having an amplitude indicative of the energy of radiation from high-energy photons impinging on the exposure surface, and(2) a conditioning circuit, operatively coupled to the detection elements, for conditioning the pulses, wherein the conditioning circuit provides low-noise amplification of the pulse.
