ABSTRACT:
A method and apparatus for recording an electroencephalogram (EEG) during magnetic resonance imaging (MRI). Nonmagnetic electrodes are attached to a patient's scalp. EEG signals are multiplexed, amplified, and transmitted to an EEG machine or a personal computer located outside the MRI room. By reducing the amount of magnetic metal and radio frequency generating equipment associated with the recording of the EEG that is within the bore of the MRI magnet, and moving all significant radio frequency generating equipment outside the MRI room, EEG signals can be recorded and MRI images can be obtained simultaneously. The EEG signals are analyzed and, in response to a predetermined pattern, the MRI machine is triggered.
