1. A method for cooling a gantry of a medical imaging apparatus, comprising:
providing a gantry forming a patient tunnel;
providing a cooling apparatus, coupled to and external the gantry, having a coolant supply for supplying fluid coolant to the gantry, and a coolant return for returning the coolant to the cooling apparatus;
orienting a first detector electronic assembly (DEA) within the gantry outboard of the patient tunnel, the DEA having:
a housing;
detector elements in the housing, for detecting incident photons of electromagnetic radiation originating outside of the housing;
other electronic components in the housing;
a fluid cooled, first chill plate in the housing that is thermally conductively coupled to the detector elements, for cooling the detector elements, the first chill plate having a first inlet for receiving the coolant from the coolant supply and a first outlet for discharging the coolant to the coolant return, the first inlet and the first outlet in communication with an exterior surface of the housing; and
a fluid cooled, second chill plate in the housing that is thermally conductively coupled to the other electronic components, for cooling the other electronic components, the second chill plate having a second inlet for receiving the coolant from the coolant supply and a second outlet for discharging the coolant to the coolant return, the second inlet and the second outlet in communication with an exterior surface of the housing;
orienting a second DEA in the gantry, having the same structure as the first DEA:
coupling directly or indirectly, the first inlet of the first chill plate of the second DEA to the coolant supply of the cooling apparatus upstream of the first DEA;
coupling the first outlet of the first chill plate of the second DEA to the respective first inlet of the first DEA;
coupling the second outlet of the second chill plate of the first DEA to the respective second inlet of the second DEA;
coupling directly or indirectly, the second outlet of the second DEA to the coolant return of the cooling apparatus; and
circulating the coolant between the gantry and the cooling apparatus at a flow rate that maintains a specified stable temperature bandwidth for all of the detector elements in both the first and second DEAs.
