title: Noise reduction in wide-bore magnets using a patient cage.
abstract: Significant rf noise reduction is demonstrated by enclosing the patient in a conducting cage grounded to the magnet bore in a 22-cm-bore spectrometer system capable of examining magnetic images and spectroscopy of human limbs. This method of noise reduction was found to be reliable, simple, and efficient for dealing with ambient rf noise in an unshielded room.
