Abstract
Methods, systems and arrangements are provided for obtaining electroencephalograph ('EEG') EEG signals from a patient e.g., during a concurrent EEG/MRI examination of the patient. The methods, systems and arrangements include a cap made of conductive inks with sensor positions for attaching a plurality of sensors to the patient's head. The sensors can include electrodes as well as motion sensors for improving EEG signal quality and MRI image quality in the presence of motion noise and other artifacts within the MRI environment. The electrodes may be composed of conductive inks, and can be used in high magnetic fields due to a weak interaction with the RF fields generated by the MRI scanner. The exemplary methods, systems and arrangements can achieve lower SAR and lower temperature increase, as compared to conventional electrodes.
