โฆ Synopsis
The performance of the rotating frame localization method is discussed, with emphasis on performing the experiment and processing the data in the optimum manner. Studies on phantom samples are presented to illustrate various imperfections which affect the confidence that can be placed on acquired data.

A spatially uniform B 1 -field is preferred for MR imaging and spectroscopy. Unfortunately, volume coils are sometimes unavailable, or do not provide adequate RF power or SNR for some applications. In quantitative MRS, mean metabolite concentration cannot be evaluated when the coil response is nonun
## Abstract A modified crossover surface coil with minimal B~1~ field penetration was used for collection of skin phosphorus NMR spectra. Projection imaging experiments show that the coilsensitive volume is uniform at the phosphorus frequency, but strikingly nonuniform at s the proton frequency. Ex
