1. A cooling system for a gantry of a diagnostic medical imaging apparatus, comprising:
a medical imaging apparatus oriented in an imaging room of a building structure;
a gantry of the medical imaging apparatus, having therein at least one electromagnetic radiation detector and a first coolant passage for absorption of heat generated within the gantry;
a solid material heatsink, having a thermal mass that receives and absorbs all heat generated within the gantry, oriented external the gantry, the heatsink defining a second coolant passage;
a coolant fluid conduit coupling the first and second coolant passages in at least one closed fluid loop; and
coolant fluid circulating within the at least one closed fluid loop of the coolant fluid conduit, for transferring heat generated within the gantry from the first coolant passage to the second coolant passage defined within the heat sink, the second coolant passage transferring the gantry heat from the coolant fluid to the heatsink by thermal conduction.
