## Abstract The technique of chemicalโshift (spectroscopic) imaging has been implemented using a variable angle adiabatic planeโrotation pulse for small angle excitation over the entire sensitive volume of a surface coil. Optimum signalโtoโnoise ratio per unit time is obtained in applications where

## Abstract Current methods for parallel excitation RF pulse design are based on the smallโtipโangle approximation, which provides a computationally efficient means of pulse calculation. In general, pulses designed with those methods are inaccurate when scaled to produce largeโtip angles, and metho
