ABSTRACT:
The signal-to-noise ratio achievable for received nuclear magnetic resonance RF signals in a magnetic resonance imaging system is increased by (a) using relatively wider strips of conductor so as to reduce coil loading by the sample and (b) the use of curved edges on a coil conductor so as to reduce "hot spots" located near the conductor surfaces.
