ABSTRACT:
A RF volume coil with optimized signal-to-noise ratio, for NMR use, has a reduced length L.sub.c, which is between about 0.3r.sub.s and about 1.5r.sub.s, where r.sub.s is the radius of a sample-to-be-investigated, contained within the cylindrical volume coil, with the volume coil radius r.sub.c being between about 1.0r.sub.s and about 1.6r.sub.s. the "short" volume coil has an improved SNR for a voxel located substantially on the central plane of the coil, relative to the SNR of a "normal"-lenth volume coil with L.sub.c .gtoreq.4r.sub.s.
