title: Automated shimming with normal spectrometer hardware: 3D profile edge shimming
abstract: A novel method is proposed for automated magnetic field homogeneity adjustment in high-resolution NMR. The method uses measurements of the edge frequencies of slice profiles recorded under static gradients to obtain three-dimensional magnetic field maps and does not require significant extra spectrometer hardware. Results are presented for the "cold" shimming of 5- and 10-mm-diameter probes in a 400-MHz narrow bore magnet. Copyright 1998 Academic Press.
