  • Multi-detector array imaging system
    Patent number: 8532251
    Abstract: An imaging system (100) includes a radiation source (108) that emits radiation that traverses an examination region (106) and a detection system (114) that detects radiation that traverses the examination region (106) and generates a signal indicative thereof. The detection system (114) includes a first detector array (1141-114N) and a second detector array (1141-114N). The first and second detector arrays (1141-114N) are separately distinct detector arrays and at least one of the detector arrays (1141-114N) is moveable with respect to the radiation beam. A reconstructor (116) reconstructs the signal and generates volumetric image data indicative thereof.

  • RADIATION DETECTOR ARRAY
    Publication number: 20090121146
    Abstract: A radiation detector module (22) particularly well suited for use in computed tomography (CT) applications includes a scintillator (200), a photodetector array (202), and signal processing electronics (205). The photodetector array (202) includes a semiconductor substrate (208) having a plurality of photodetectors and metalization (210) fabricated on non-illuminated side of the substrate (208). The metalization routes electrical signals between the photodetectors and the signal processing electronics (205) and between the signal processing electronics (205) and an electrical connector (209).
