Abstract
A sensor device intended to be implemented at the vicinity or inside a nuclear magnetic resonance apparatus, and more particularly on a patient inside the canal of the magnet of a magnetic resonance imager (MRI). The device includes at least two non-metal electrodes intended to be applied to the skin of a patient, and an electro-optical conversion, amplification and filtering module for the electric signals received from the heart by the electrodes. The module is arranged in a shielded casing forming a Faraday cage, and optically connected to a display and/or monitoring apparatus. A support body made of non-magnetic material carries the electrode and the shielded casing containing the module.
