1. A cooling channel for a gantry of a diagnostic medical imaging apparatus, comprising:
a non-metallic housing having a lower surface, for abutting contact and coupling to an electromagnetic radiation detector, and an upper surface for abutting contact and coupling to a detector electronics package;
a cooling conduit in the housing, for circulation of coolant fluid therethrough, the conduit having an inlet and an outlet respectively accessible outside the housing, and an exterior surface profile;
a unitary, non-metallic heat sink in the housing, having:
respective continuous top and bottom surfaces in direct heat-conductive communication with the respective upper and lower surfaces of the housing, and
a lateral surface between the top and bottom surfaces, having an exterior surface profile conforming to the exterior surface profile of the conduit, in opposed, spaced orientation with the conduit; and
a solid, thermally conductive layer interposed between and affixed to the respective opposed, exterior surface profiles of the conduit and the heat sink.
