Abstract
Presented is a straightforward derivation of the effective sample resistance presented to the input amplifier of a nuclear magnetic resonance imager when flat circular surface coils are used to image lossy media. The resistance may be used to determine sample noise following the method of Hoult and Lauterbur.Keywords
