A radio frequency (RF) receiving coil unit for a magnetic resonance imaging (MRI) system, the RF receiving coil unit comprising:
- an RF coil;
- a first circuit configured to comprise a first coil and obtain a bias control signal in response to a comparison result between a current flowing through the RF coil and a predetermined threshold value by using an electromagnetic coupling between the RF coil and the first coil;
- and
- a second circuit configured to obtain a signal for stopping scanning using a PIN bias switch based on the bias control signal.
A radio frequency (RF) receiving coil unit for a magnetic resonance imaging (MRI) system, the RF receiving coil unit comprising:
- an RF coil;
- a cable configured to transmit a signal received by the RF coil;
- and
- a first circuit comprising a first coil and configured to obtain a bias control signal in response to a comparison result between a current flowing through the cable by using electromagnetic coupling between the cable and the first coil;
- and
- a second circuit configured to obtain a signal for stopping scanning using a PIN bias switch based on the bias control signal.
A method for a magnetic resonance imaging (MRI), comprising:
- transmitting, by a cable, a signal received by a radio frequency (RF) coil;
