Abstract: An energy-sensitive computed tomography system is provided. The energy-sensitive computed tomography system includes an X-ray source configured to emit an X-ray beam resulting from electrons impinging upon a target material. The energy-sensitive computed tomography system also includes an object positioned within the X-ray beam. The energy-sensitive computed tomography system further includes a detector configured to receive a transmitted beam of the X-rays through the object. The energy-sensitive computed tomography system also includes a filter having an alternating pattern disposed between the X-ray source and the detector, the filter configured to facilitate measuring projection data that can be used to generate low-energy and high-energy spectral information.

Abstract: An interface assembly for a sensor array is provided. The interface assembly may be made up of an integrated circuit package thermally coupled to the sensor array. The interface assembly may include a temperature control system for controlling the temperature of the sensor array. The temperature control system includes a temperature sensor for sensing a temperature variation of each sensor of the sensor array from an initial temperature beyond a predetermined threshold. A temperature controller is coupled to each temperature sensor and receives an output signal from the temperature sensor upon the sensor temperature variation exceeding the predetermined threshold. A temperature correction device is coupled to each temperature controller and causes the sensor temperature variation to fall within the predetermined threshold upon receiving a control signal from the temperature controller.

Abstract: A detector assembly is presented. The detector assembly includes a first detector layer having a top side and a bottom side, where the first detector layer includes a plurality of first coupling gaps. Additionally, the detector assembly includes a first interconnect structure operationally coupled to the first detector layer and configured to facilitate transfer of a first set of image data from the first detector layer to backplane electronics. The detector assembly also includes a second detector layer having a top side and a bottom side and disposed adjacent the bottom side of the first detector layer, where the second detector layer includes a plurality of second coupling gaps configured to facilitate passage of the first interconnect structure from the first detector layer to the backplane electronics.

Abstract: Various configurations for scatter reduction and control are provided for CT imaging. These configurations include an imaging system having a stationary detector extending generally around a portion of an imaging volume and a distributed X-ray source placed proximal to the stationary detector for radiating an X-ray beam toward the stationary detector. A scatter control system is further provided that is configured to adaptively operate in cooperation with the stationary detector and the distributed X-ray source to focally align collimator septa contained therein to the X-ray beam at a given focal point and to provide X-ray beam scatter control.
