Abstract:
A method is provided for producing, with a magnetic resonance (MR) system, a nuclear magnetic resonance spectrum that has been corrected for errors arising from phase offsets and time shifts in the acquired spectroscopic data. A spectroscopic data set includes temporal information indicative of the underlying phase offsets and time shifts. In general, this temporal information is utilized to correct for errors in the acquired data. As a result, a plurality of acquired spectroscopic data sets are more accurately combined by first individually correcting each spectroscopic data set for such errors. Exemplary sources of the phase offsets and time shifts include the physical separation between a volume of interest and the detectors in the MRI system. Using the temporal information, Tdecay in the produced spectrum is also corrected.
