  • Publication number: 20040196043
    Abstract: An apparatus and method for providing RF shielding for performing nuclear magnetic resonance (“NMR”) procedures, comprising a radio-opaque holder in combination with radio-opaque magnet components to form an RF shield around a patient undergoing an NMR procedure. In embodiments, a radio-opaque holder having a radio-opaque bottom portion and a radio-opaque canopy is adjoined to an NMR magnet having a radio-opaque cryostat and a radio-opaque service end cap to form an RF shield. A patient is placed on a patient support unit located in the holder bottom portion. The patient support unit, including the patient, is then inserted into the cavity of the NMR magnet and a canopy is placed on top of the bottom portion of the holder. An RF shield is thus created comprising the canopy, the bottom portion, the cryostat of the magnet, and an end cap on the service end of the magnet.

  • Publication number: 20030178995
    Abstract: A magnetic resonance imaging (“MRI”) system and method of correcting for the motion of a subject during an MRI scan. The motion of a subject in an MRI scan is corrected by acquiring nuclear magnetic resonance (“NMR”) spectra of an ordered material attached to a subject, wherein there is a dependence on the NMR spectra of the ordered material's orientation in a magnetic field, and determining an orientation of the subject. Correction information is then supplied to a primary spectrometer channel which is used to execute an MRI scan, and an imaging pulse sequence of the MRI scan is adjusted to correct the subject's orientation.
