Distributed phase rf coil

摘要: Apparatus for generating and detecting magnetic field components oscillating at a radio frequency in direction transverse to static nuclear-magnetic-resonance (NMR) system. The apparatus has plurality of conductive elements spaced from one another the axis along which is directed. relative amplitudes alternating currents are controlled generate spatially uniform field. A preferred embodiment uses standing wave coil assembly control current amplitudes, takes advantage current-phase characteristics such waves. Detection RF fields results an EMF generated response time-varying field; high Q enhances detection properties.
