ABSTRACT:
A computed tomography (CT) system comprises an X-ray radiation source to project a plurality of X-ray beams through an object and a detector array comprising a plurality of detector assemblies. Each of the detector assembly further comprises a detector subassembly adapted to detect the X-ray beams and further adapted to convert the X-ray beams to a plurality of electrical signals and at least one integrated circuit array, for example, data acquisition chip array to acquire data corresponding to the electrical signals. The integrated circuit array, for example, data acquisition chip array further comprises a plurality of integrated circuits, such as, data acquisition chips mounted on at least one printed circuit board and a thermal management system adapted for thermal communication between the data acquisition chip array and a heat sink assembly to control thermal environment of each detector assembly. The heat sink further comprises a spreader plate extending over 2 or more data acquisition chips to reduce the temperature difference within the data acquisition chips.
