Abstract:
A radio frequency (RF) coil assembly for use in magnetic resonance includes a radio frequency coil (42, 100) and an electronic switch (28) which switches between open and closed states to detune and tune the coil to a preselected resonance frequency. Each electronic switch includes at least one field effect transistor (FET) (70) and a bias network (72).
