Patent ID: 8390285

Claim:
A method for side-band suppression in magnetic resonance (MR) signals comprising the steps of: in a computerized processor, determining a positive eddy current correction factor and a negative eddy current correction factor; operating an MR spectroscopic data acquisition unit with an examination subject therein to scan the subject N/2 times with an MR spectroscopic data acquisition sequence comprising a positive gradient, and collecting a positive gradient scanning signal during each scan with the positive gradient and to scan the subject N/2 times with an MR spectroscopic data acquisition sequence comprising a negative gradient, and collecting a negative gradient scanning signal during each scan with the negative gradient, wherein N is an even number; in said processor, performing an eddy current correction of the N/2 positive gradient scanning signals collected according to said positive eddy current correction factor, and performing an eddy current correction of the N/2 negative gradient scanning signals collected according to said negative eddy current correction factor; and in said processor, calculating a side-band suppressed spectrum signal according to the N/2 positive gradient scanning signals that have undergone the eddy current correction and the N/2 negative gradient scanning signals that have undergone the eddy current correction.
