  • System and method providing preamplifier feedback for magnetic resonance imaging
    Patent number: 8791696
    Abstract: A system and method for generating preamplifier feedback in magnetic resonance imaging (MRI) systems are provided. A preamplifier arrangement for the MRI system includes a plurality of preamplifiers with each of the preamplifiers connected to a different channel of a multi-channel coil array of the MRI system. The preamplifier arrangement further includes a feedback network connected to each of the plurality of preamplifiers with each of the feedback networks configured to generate negative feedback at one or more oscillation frequencies.
    Type: Grant

  • MRI Phase Visualization of Interventional Devices
    Publication number: 20090102479
    Abstract: Imaging a device in a magnetic resonance imaging system includes inserting a device having a conductive coil assembly thereon into a subject, obtaining a magnetic resonance image of the subject that includes signal phase variations, determining a position of the device based on discontinuities in the signal phase variations, and displaying an image representation of the device superimposed on a reference image based upon the determined position.
