An MR system isolation impedance mismatch apparatus ( ) includes an impedance mismatch layer ( ). The impedance mismatch layer ( ) performs as a mechanical notch filter and isolates an MR system component ( ) from a surrounding structure ( ). A method of tuning the impedance mismatch apparatus ( ) includes determining a default notch filter frequency range. The impedance mismatch apparatus ( ) is formed and performs as a notch filter having the default notch filter frequency range. The impedance mismatch apparatus ( ) is installed and tested between the MR system component ( ) and the surrounding structure ( ). Vibrations are detected in the MR system component ( ) and in the surrounding structure ( ). The impedance mismatch apparatus is adjusted in response to the detected vibrations.

Impedance mismatch apparatus and system for isolation of an MR imaging system

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.
