Abstract
La présente invention concerne un procédé et un appareil d'analyse ou de détection d'états pathologiques, de sites de lésions ou d'états somatiques chez l'homme ou l'animal, lesquels procédé et dispositif opèrent par détections séparées du biopotentiel de courant continu de champs électromagnétiques au niveau d'une pluralité de points de tests d'une zone de tests. Des convertisseurs analogique-numérique (36, 38) connectés aux capteurs (12) de tests de biopotentiel de courant continu situés sur les points de tests convertissent ces biopotentiels de courant continu en signaux de tests numériques. Ces capteurs (12) de tests de biopotentiel ainsi que les convertisseurs analogique-numérique (36, 38) forment un module de détection (48) du biopotentiel qui est distinct d'un module de traitement (46) recevant et traitant les signaux de tests. Les signaux sont transmis entre le module de traitement (46) et le module de détection (48) du biopotentiel par un réseau de transmission isolant électriquement les deux modules. Les conversions réalisées par les convertisseurs analogique-numérique (36, 38) sont synchronisées avec la fréquence de ligne de courant alternatif de l'alimentation électrique (42) de l'appareil. Des filtres numériques (68) du module de traitement (46) filtrent les signaux de tests numériques, chaque filtre numérique étant spécifiquement affecté à un capteur de tests (12) particulier de biopotentiel de courant continu.
