Abstract: In one embodiment, a system for thermal management in a CT device comprises first and second thermal management zones, each comprising an x-ray detector, at least one variable speed fan proximate to the x-ray detector, an air temperature sensor positioned to measure an air temperature of the intake air to the variable speed fan, a rail heater in thermal contact with the x-ray detector, a rail temperature sensor in thermal contact with the rail heater to measure a rail temperature, and a controller that controls the variable speed fan as a function of at least the air temperature and the rail heater as a function of the rail temperature to maintain a temperature of the x-ray detector within a predetermined range.

Abstract: A CT system includes a rotatable gantry having an opening for receiving an object to be scanned, an x-ray source configured to project x-rays through the opening, and a detector assembly positioned to receive the x-rays. The detector assembly includes a plurality of readout chips positioned within a cooling zone and configured to receive electrical signals from a plurality of diode arrays, and a fan positioned to blow air into the cooling zone. An air temperature within the cooling zone is controlled independent of a speed of the fan.
