The utility of remote sensing in the study of fluvial systems depends upon the extent to which image data can be used to derive quantitative information of sufficient accuracy and precision for specific applications. In this study, we evaluate the effects of channel morphology on depth retrieval by

A modified version of the echo-planar imaging technique incorporating a Carr-Purcell train of 180 degrees rf pulses (PEPI) has been implemented on a standard spectrometer. It is demonstrated that artifacts in the image due to cumulative errors in the rf field can be reduced by replacing each 180 deg

## Abstract Several aspects of blipped echo‐planar imaging (EPI) are treated mathematically. An expression relating the necessary readout gradient strength and sampling time to the spatial resolution and readout duration is derived. It is shown how the net spatial resolution may be limited by the o

In studies of 31P metabolite imaging in the human brain using a high-field 4.1 T NMR system, resolution and signal-to-noise ratios were measured to determine the potential for spatial-resolution improvements. The results suggest that spatial resolution of FWHM of 2 cm or less, similar to that of rad
