Abstract

Se presenta un método y un aparato para explorar o sensar estados de enfermedad, lugares de daño o condiciones corporales en un sujeto humano o animal al detectar separadamente el biopotencial CD del campo electromagnético en una pluralidad de puntos de prueba en un área de ensayo. Los biopotenciales CD son convertidos análogo a digital (36, 38) conectados a sensores de prueba biopotenciales Cd (12) en los puntos de prueba a señales de prueba digitales, y los sensores de prueba biopotencial CD (12) y los convertidos de análogo a digital (36, 38) forman una seccion sensora biopotencial (48) que está separada de una seccion procesadora (46) que recibe y procesa las señales de prueba. Las señales entre la seccion procesadora (46) y la seccion sensora biopotencial (48) se transmiten por una red de transmision que aísla electricamente las dos secciones. La conversion realizada por los convertidores (36, 38) están sincronizadas con la frecuencia de línea CA del suministro de energía o electricidad del aparato (42) y las señales de prueba digitales son filtradas en la seccion procesadora (46) por filtros digitales (68), cada uno de los cuales está dedicado a un sensor de prueba biopotencial (12) CD individual.
