The present invention relates to a magnetic stimulation (MS) coil arrangement which utilises the effect of the position of a ferromagnetic material to enhance the magnetic field on the patient side of the coil and reduce acoustic noise associated with the addition of ferromagnetic material. The present invention comprises a magnetic stimulation coil arrangement comprising one or more coil windings formed from an elongate conductive element and having a forward side for presentation to a patient and a rearward side, the magnetic stimulation coil arrangement further comprising a distortion arrangement for distorting a magnetic field produced by the one or more coils positioned adjacent to the rearward side, the distortion arrangement having a plurality of ferromagnetic components and a carrier for carrying the ferromagnetic components, the ferromagnetic components being spaced from one another by the carrier.
A magnetic stimulation coil arrangement for use in apparatus for the magnetic stimulation of tissue, the magnetic stimulation coil arrangement comprising one or more coil windings formed from an elongate conductive element and having a forward side for presentation to a patient and a rearward side, the magnetic stimulation coil arrangement further comprising a distortion arrangement for distorting a magnetic field produced by the one or more coils positioned adjacent to the rearward side, the distortion arrangement having a plurality of ferromagnetic components and a carrier for carrying the ferromagnetic components, the ferromagnetic components being spaced from one another by the carrier.
A magnetic stimulation coil arrangement for use in apparatus for the magnetic stimulation of tissue, the magnetic stimulation coil arrangement comprising one or more coil windings formed from an elongate conductive element and having a forward side for presentation to a patient and a rearward side, the magnetic stimulation coil arrangement further comprising a distortion arrangement for distorting a magnetic field produced by the one or more coils positioned adjacent to the rearward side, the distortion arrangement having a plurality of ferromagnetic particles dispersed therein and a carrier for carrying the ferromagnetic particles, the ferromagnetic particles being spaced from one another by the carrier wherein the ratio volume of ferromagnetic particles to carrier material is less than 1.5:1.
