Abstract

"ESTIMULADOR SENSORIAL", Compreendendo um receptáculo (10) assentável contra uma parte do corpo de um paciente sendo submetido a exame em um aparelho de ressonância magnética; uma bobina (30) montada no interior do receptáculo (10) e energizável a partir de uma fonte de corrente contínua (40) com polaridade sendo invertida a uma frequência predeterminada, de modo a produzir um campo magnético suficiente para provocar, por interferência com o campo magnético do aparelho de ressonância magnética, a vibração da bobina (30) no interior do receptáculo (10) a uma frequência correspondente à frequência de inversão de polaridade da corrente fornecida pela fonte de corrente contínua (40)."SENSORIAL STIMULATOR", Comprising a receptacle (10) that can be seated against a part of a patient's body being subjected to examination in an MRI machine; a coil (30) mounted inside the receptacle (10) and energizable from a direct current source (40) with polarity being inverted at a predetermined frequency, in order to produce a magnetic field sufficient to cause, by interference with the magnetic field of the magnetic resonance apparatus, the vibration of the coil (30) inside the receptacle (10) at a frequency corresponding to the frequency of polarity inversion of the current supplied by the direct current source (40).
