  • Inventor(s):
    Ken D. Sauer, Charles A. Bouman, Jean-Baptiste Thibault, Jiang Hsieh
    Patent Number:
    US 6907102 B2
    Description:

    A multi-slice computed tomography imaging system is provided including a source that generates an x-ray beam and a detector array that receives the x-ray beam and generates projection data. A translatable table has an object thereon and is operable to translate in relation to the source and the detector array. The source and the detector array rotate about the translatable table to helically scan the object. An image reconstructor is electrically coupled to the detector array and reconstructs…
