Abstract

Using the technique of separable k‐space excitation, we have designed a two‐dimensional selective adiabatic pulse that inverts magnetization from a square region in the xy plane with insensitivity to RF variations. We also have designed a two‐dimensional adiabatic pulse that inverts selectively in frequency and in one spatial dimension. The pulses should be useful for both MR imaging and spectroscopy. We present experimental results to demonstrate that the two‐dimensional adiabatic pulses are feasible on commercial MR imaging systems. © 1992 Academic Press, Inc.

Adiabatic RF pulses play an important role in spin inversion where G is the adiabatic parameter due to their robust behavior in presence of inhomogeneous RF fields. These pulses are characterized by the trajectory swept by the tip of the B eff vector and the rate of motion upon it. In this paper, a

Many types of NMR experiments demand the use of frequencyselective pulses to invert magnetization within discrete frequency limits. For certain experiments, only one side of the inversion band must be sharply demarcated, in which case this transition bandwidth can be narrowed when using an asymmetri
