  • Impedance mismatch apparatus and system for isolation of an MR imaging system
    Patent number: 6791325
    Abstract: An MR system isolation impedance mismatch apparatus (12) includes an impedance mismatch layer (24). The impedance mismatch layer (24) performs as a mechanical notch filter and isolates an MR system component (14) from a surrounding structure (18). A method of tuning the impedance mismatch apparatus (12) includes determining a default notch filter frequency range. The impedance mismatch apparatus (12) is formed and performs as a notch filter having the default notch filter frequency range. The impedance mismatch apparatus (12) is installed and tested between the MR system component (14) and the surrounding structure (18). Vibrations are detected in the MR system component (14) and in the surrounding structure (18). The impedance mismatch apparatus is adjusted in response to the detected vibrations.

  • Non-conductive long wave thermal radiation shield
    Patent number: 6538440
    Abstract: A thermal radiation shield 44 and a method for applying the same includes a first coating layer 46, a second coating layer 48, and a thermal shield layer 50. The first coating layer 46 is applied to a first surface. The second coating layer 48 is applied to a second service. The thermal shield layer 50 is positioned between the first coating layer 46 and the second coating layer 48 to form the thermal radiation shield 44. The thermal radiation shield 44 has non-interfering electrical properties.

  • Low noise MRI scanner
    Patent number: 6437568
    Abstract: A low noise imaging apparatus for producing Magnetic Resonance (MR) images of a subject and for substantially minimizing acoustic noise generated during imaging is provided. The imaging apparatus comprises a magnet assembly, a gradient coil assembly, and a rf coil assembly, wherein at least one of the magnet assembly, the gradient coil assembly and the rf coil assembly are configured to reduce the generation and transmission of acoustic noise.
