Abstract:
A tuning/detuning structure and a detuning method for an RF coil use an RF power source, a first impedance circuit, a first RF line, and a first port having a first guide leg end and a first input end, with the first guide leg end being connected to a first end ring capacitance of the RF coil. When the RF coil needs to be detuned, the first input end is connected to the first impedance circuit via the first RF line. When the RF coil needs to transmit an RF pulse signal, the first input end is connected to the RF power source via the first RF line. The need for a switch element is thereby reduced as is harm resulting from breakdown of such a switch element. An impedance circuit can be combined with a switch element to realize detuning jointly, and a good detuning effect can be achieved by a small number of switch elements.

Claim (Index 1):
An RF coil tuning/detuning circuit, comprising:\n an RF power source; a first impedance circuit, arranged independently of the RF power source; a first RF line; a first port comprising a first guide leg end and a first input end, with the first guide leg end being connected to a first end ring capacitance of the RF coil; when the RF coil needs to transmit an RF pulse signal, the first input end is connected to the RF power source via the first RF line; when the RF coil needs to be detuned, the first input end is connected to the first impedance circuit via the first RF line.
