Abstract

DISPOSITIVO, APARELHO, MÉTODO DE OPERAÇÃO DE UM DISPOSITIVO E PROGRAMA DE COMPUTADOR. A presente invenção refere-se a um dispositivo (100) e a um método para fazer a interface entre um dispositivo de transmissão/recepção de sinal (200) e um cateter (300). Um sinal transmitido pelo dispositivo de transmissão/recepção de sinal (200) e transmitido ao dispositivo (100) por meio de uma primeira interface (102, 104, 106, 108) pode ser detectado por um primeiro sensor (114). O sinal detectado pode ser ajustado por uma unidade de ajuste (116). O sinal ajustado pode ser emitido por meio de uma segunda interface (110, 112) e transmitido ao cateter (300). Dessa. maneira, .uma perda de resistência causada pelo condutor (302, 304) de um cateter (300) pode ser compensada.
