Abstract

"PERCEPçãO DE POSIçãO COM BASE EM MAGNéTICO HìBRIDO E COM BASE EM IMPEDáNCIA". A presente invenção refere-se a um sistema de percepção de posição inclui uma sonda adaptada para ser introduzida em uma cavidade corporal de um indivíduo. A sonda inclui um transdutor de campo magnético e pelo menos um eletrodo de sonda. Uma unidade de controle é configurada para medir as coordenadas de posição da sonda usando o transdutor de campo magnético. A unidade de controle também mede uma impedância entre o pelo menos um eletrodo de sonda e um ou mais pontos em uma superfície corporal do indivíduo. Usando as coordenadas de posição medidas, a unidade de controle calibra a impedância medida.
