The local transceiver coil such as a birdcage coil has still been equipped for local extremity or brain MRI in clinical study. By accident, the local transceiver coil is disconnected from an MRI system and inadvertently leaves linked to strong MRI RF fields during imaging procedures using other RF coils. It makes the local transceiver coil damaged such as components burnt as well as worse plastic housing melt and even causes patients’ skin to burn during clinical scanning. To prevent from these damages, we propose a new protection circuit to prevent the unplugged local transceiver coil in MR bore from RF power radiated by the whole body transmitter coil.
