Abstract
A system for remontaging EEG signals includes acquiring a first set of bipolar signals in a first montage defined by the locations of electrodes on a patient, synthesizing a second set of bipolar signals corresponding to a second montage defined by the electrode locations, and displaying, printing, or recording the second set of signals. Preferably, the first set of bipolar signals is converted to a set of monopolar signals, from which bipolar signals corresponding to any desired montage defined by the electrode location may be synthesized. This system permits remontaging of signals without the drawbacks of existing remontaging systems, which use monopolar signal acquisition.
