Abstract: In order to provide interventional access during an image-guided interventional procedure, while increasing the signal-to-noise ratio for generated images compared to a single loop coil, a local coil includes a single coil element disposed around an opening through the local coil and two coil elements positioned on opposite sides of the single coil element. The opening provides access for an interventional tool used during the image-guided interventional procedure.
Abstract: An electrically-controlled failsafe switch is included in an MRI transmit-and-receive RF coil assembly so as to protect it from induced RF currents in the event it is disconnected from an MRI system, but inadvertently left linked to strong MRI RF fields during imaging procedures using other RF coils.
