Title (EN) MULTI-COIL TRANSCRANIAL MAGNETIC STIMULATION
(FR) STIMULATION MAGNÉTIQUE TRANSCRANIENNE À BOBINES MULTIPLES
Abstract:
(EN) An improved apparatus is provided for transcranial magnetic stimulation in a brain of a subject. The apparatus is comprised of: a plurality of coils electrically connected in series to each other; and a single source of current electrically coupled to one of the plurality of coils. Each coil may include one or more windings of similar dimensions although the size of the windings varies between coils. Each of the coils is further dimensioned to stimulate brain tissue at a given distance while minimizing volume of the brain tissue excited by the magnetic field. During operation, the current source injects time varying current into the coils to create a magnetic field which in turn induces electric fields and eddy-currents inside the brain tissue of the subject.
(FR) L'invention concerne un appareil amélioré destiné à la stimulation magnétique transcranienne dans le cerveau d'un sujet. L'appareil comprend une pluralité de bobines interconnectées électriquement en série et une source unique de courant couplée électriquement à l'une des bobines faisant partie de la pluralité de bobines. Chaque bobine peut comprendre un ou plusieurs enroulements de dimensions similaires, bien que la taille des bobines puisse varier entre les bobines. Chaque bobine présente en outre des dimensions choisies pour stimuler le tissu cérébral excité à une distance donnée, le volume du tissu cérébral excité par le champ magnétique étant alors réduit au minimum. Pendant le fonctionnement, la source de courant injecte du courant variant dans le temps dans les bobines pour créer un champ magnétique qui à son tour induit des champs électriques et des courants de Foucault dans le tissu cérébral du sujet.
