Title:
APPARATUS FOR DYNAMIC ANGULAR POSITION TRACKING
Document Type and Number:
WIPO Patent Application WO2003082401
Kind Code:
A3
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.
