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.
Claims9
In a detector device for electrocardiograms, adapted to be used in a loaded and sensitive electromagnetic environment, adjacent or within a nuclear magnetic resonance apparatus, and on a patient within the tunnel of the magnet of a magnetic resonance imager (MRI), the improvement wherein the device comprises at least two non-metallic electrodes for application to the patient's skin for receiving electrical signals from the heart;
- a module including means for filtering the electrical signals received from the heart, means for amplifying filtered signals, and means for electro-optically converting filtered and amplified electrical signals, said module being disposed in a shielded housing forming a Faraday cage;
- an optical means connecting said casing to an apparatus for visualization;
- and a support body of an amagnetic material carrying the shielded housing containing the module, said support body including means for maintaining the shielded housing at a constant distance from the patient's skin.
