  • Publication number: 20040264632
    Abstract: A computed tomography (CT) system comprises an X-ray radiation source to project a plurality of X-ray beams through an object. A detector array comprises a plurality of detector assemblies. A gantry secured to the X-ray radiation source and the detector array rotates around a longitudinal axis. Further, each of the detector assembly comprises a detector subassembly adapted to detect the X-ray beams. These detector subassemblies are further adapted to convert the X-ray beams to a plurality of electrical signals. At least one circuit board assembly is coupled to the detector subassembly. The circuit board assembly typically comprises an integrated circuit array, such as, data acquisition chip array to acquire data corresponding to the electrical signals. The integrated circuit array further comprises a plurality of integrated circuit chips, for example, data acquisition chips mounted on at least one printed circuit board.

  • Publication number: 20040120148
    Abstract: A lamp having a lighting source, integral electronics, and a thermal distribution mechanism disposed in a housing. The thermal distribution mechanism may include a variety of insulative, radiative, conductive, and convective heat distribution techniques. For example, the lamp may include a thermal shield between the lighting source and the integral electronics. The lamp also may have a forced convection mechanism, such as an air-moving device, disposed adjacent the integral electronics. A heat pipe, a heat sink, or another conductive heat transfer member also may be disposed in thermal communication with one or more of the integral electronics. For example, the integral electronics may be mounted to a thermally conductive board. The housing itself also may be thermally conductive to conductively spread the heat and convect/radiate the heat away from the lamp.
