| 摘要 |
A circuit for active decoupling of transmit coils in Nuclear Magnetic Resonance imaging apparatuses, particularly of the low field type, includes at least one PIN diode (D1), which is connected in series with the conductors of at least one transmit coil (1) and has at least one input (4) for an incoming bias current. The circuit has at least one additional diode (D2) which is a silicon diode connected in antiparallel with the PIN diode (D1).
