Abstract:
1. A temperature sensor configured to detect heating of at least one electrode pole of an implantable electrode line having at least one elongated electrical conductor which is connected to the at least one electrode pole, during a nuclear spin tomography or magnetic resonance tomography (MRT), comprising: an impedance detection unit that is a magnetic resonance tomography (MRT) sensor configured to respond to a presence of MRT-typical magnetic fields and to generate an output signal which indicates the presence of the MRT-typical magnetic fields; and wherein the temperature sensor is configured to separate a temperature-related impedance curve from impedance curves based on causes other than temperature-related causes, through use of a reference impedance curve which was recorded and stored during times in which no nuclear spin tomography or magnetic resonance tomography (MRT) took place.
