Abstract
A device for monitoring a living object during a magnetic resonance (MRI) experiment in an MRI tomograph, wherein the device comprises one or more individual electrodes which are connected in an electrically conducting fashion to the living object to be examined, and are connected to a monitoring device via signal lines, wherein each signal line comprises individual parts that are electrically connected to each other via impedances. The eigenfrequencies of these parts are higher than the NMR measuring frequency, preferably more than twice as high, and the parts are electrically connected to each other via frequency-dependent impedances Zn. The electro-magnetic coupling from the RF antenna and the gradient coils to the signal lines can thereby also be minimized in a simple fashion.
