  • Pulsable superconducting coil setup for magnetically sensitive operations
    Patent number: 11500049
    Abstract: The invention relates to a device for magnetic measurements and/or magnetic imaging such as an MRI device or a hybrid MEG-MRI device. The device comprises an array of one or more detectors for the magnetic signal and one or more coils for producing preparatory magnetic field pulses. The device further comprises means to drive current pulses through the said coils, wherein at least one of the coils comprises material that is Type-II superconducting at the operating temperature. The device is configured to cancel out at least part of the field generated by the remanent magnetization after a current pulse by the shape of the current pulse and/or the geometrically balanced design of the coil.
    Type: Grant
