发明名称 MAGNETIC RESONANCE IMAGING METHOD AND APPARATUS TO CORRECT DISTORTIONS DUE TO INHOMOGENEITIES OF THE BASIC MAGNETIC FIELD
摘要 In a magnetic resonance method and system to correct spatial shifts in MR data, at least two measurement data sets are acquired, the additional measurement data set or sets being acquired while switching an additional gradient relative to acquisition of the first measurement data set. For respective corresponding measurement points of the measurement data sets, a phase difference is initially determined from the first measurement data set and at least one additional measurement data set acquired with the additional gradient, with a spatial shift of the measurement points of the first measurement data set being determined from the spatial shift. The magnitude values of the initially measured measurement points are distributed to their correct spatial position corresponding to the determined spatial shifts, so a corrected image data set is created.
