Abstract

Nuclear magnetic resonance (NMR) rotating (ρ) pulses produce two-dimensional spatially selective inversion of nuclear magnetization with a single NMR excitation. A technique employing frequency modulation of the excitation waveform is described here for offsetting the sensitive volume defined by these pulses to any preselected location within the sample. The technique is demonstrated in a whole-body 1 H NMR imaging system, and can be used to provide simple, automated relocation or interleaving of selectively excited volumes in NMR imaging and spectroscopy.
