Abstract

Un sistema de electrodos incluye un electrodo, un conector y un cable con un módulo de filtro de radiofrecuencia en línea que comprende resistencias e inductores sin capacitancia añadida deliberadamente. Las resistencias son dispuestas en una serie alterna de resistencias e inductores, preferiblemente con resistencias en ambos extremos externos y conectadas eléctricamente en serie. El módulo en línea es ubicado en una ubicación específica a lo largo del cable, elegida a través de modelado por computadora y pruebas del mundo real para transferencia mínima de energía de RF recibida a la piel de un paciente, tal como entre 100 cm y 150 cm del extremo de electrodo de un Cable de 240 centímetros. La resistencia total de las resistencias más el cable, conectores y soldadura es de 1000 ohmios o menos; mientras que la inductancia total es de aproximadamente 1560 nanohenries. Los inductores no incluyen ferrita u otro material magnético y son, junto con las resistencias, componentes de stock, lo que simplifica la fabricación y reduce los costos.
