Abstract: A plurality of magnetic field induction coils and a radio frequency (RF) detection coil are supported by a frame which is inserted into the bore of an MRI system to detect magnetic fields produced by gradient pulses and RF pulses produced during a scan. The detected magnetic fields are processed to produce gradient waveforms and RF pulse waveforms that are displayed to the user.

Abstract: An apparatus for supporting a patient support bridge member in an MR system where a first end of the bridge is supported by an upright support member on a first side of an MR imaging bore and the bridge extends through the bore so that a second end of the bridge extends out a second side of the bore, the apparatus including a bracket mounted to an MR main magnet on the second side of the bore and extending upwardly to contact and support the bridge there above.

Abstract: Monitor signals are acquired in an interleaved manner during a scan with an MRI system. Frequency changes caused by variations in the polarizing magnetic field B0 are measured using the monitor signals, and these measured frequency changes are employed to compensate image data acquired during the scan.

Abstract: Correcting gradients for a phase encoding axis in an MRI imaging system are provided in an FSE pulse sequence to correct phase errors in echo signals, such as due to effects of cross term eddy currents induced by slice select gradients. Correcting gradients to be applied to the logical phase encoding axis are identified in a prescan sequence. An initial correcting gradient is identified for correcting phase errors resulting from an initial slice select gradient pulse. Subsequent, bipolar gradient pulses for the phase encoding axis are then derived from the initial correcting gradient. The prescan technique may be used in conjunction with other prescanning sequences used to determine additional corrections for the FSE sequence. The correcting gradients reduce or eliminate image artifacts resulting from such factors as cross term eddy currents in oblique scans. An averaging sequence may be implemented to reduce the likelihood for influencing the compensation pulse calculation errors.
