  • RF transmission circuit, complex digital synthesizer, and MRI apparatus
    Patent number: 6862435
    Abstract: An RF transmission circuit, complex digital synthesizer and MRI apparatus are intended to enhance the stability of signal quantity and reduce the cost, wherein a complex digital synthesizer generates reference carrier frequency signal data directly in the digital domain, RF envelope mixers combine the resulting data and RF envelope signal data in the digital domain, and a digital frequency up-converter up-converts the resulting signal data in the digital domain and converts into an analog RF pulse signal.
    Type: Grant
    Filed: July 3, 2002
    Date of Patent: March 1, 2005
    Assignee: GE Medical Systems Global Technology, LLC
    Inventors: Hiroyuki Miyano, Masakazu Kinomoto
