  • Inventor(s):
    Jiang Hsieh, Jean-Baptiste Thibault, Charles A. Bouman, Ken D. Sauer
    Patent Number:
    US 6768782 B2
    Description:

    An imaging system is provided including a source generating an x-ray beam and a detector array receiving the x-ray beam and generating projection data corresponding to at least a scanned portion of an object. An image reconstructor is electrically coupled to said detector array and reconstructs an image of the scanned portion of the object for a full field-of-view in response to said projection data using a dual iterative reconstruction technique. The dual iterative reconstruction technique i…

    Patent Number:
    US 7639628 B2
    Description:

    A method that includes activating and deactivating two counts between an active state and not an active state such that no more than one count at a time is in an active state. The method also includes receiving a request packet of information that requires a reply and incrementing the count that is in an active state, and setting a flag in the request packet of information that requires a reply, the flag being set to correspond to the count that is in the active state. The method further incl…

    Patent Number:
    US 6363103 B2
    Description:

    A multistage or parallel interference canceler (PIC) arrangement is disclosed for use in a communications system using code division multiple access (CDMA) with M-ary orthogonal modulation. All the M symbol waveforms, weighted according to their correlations with a despread signal, are combined to form a reconstructed symbol waveform for each user in each stage. The reconstructed symbol waveforms for all users are summed to form an estimated composite received signal having reduced interferen…
