This paper summarizes our initial clinical results from an ongoing combined high-density Electroencephalogram (hdEEG) and Electrical Impedance Tomography (EIT) pilot study on stroke patients. Stroke is a major global problem affecting millions of people. Improvements in care can be made in earlier diagnosis of stroke type and in monitoring or predicting outcomes. We report on the first four stroke patients we have recruited, as well as prelminary results of our iPhone scanning/electrode registration technique of a 256-electrode hdEEG cap. Higher conductivity is found in 2 of 4 patients where the stroke is located, a third patient had a very mild stroke (NIHSS=0) and EIT was not able to detect it -- but otherwise is consistent with the initial two patients, and the last case appeared to have artifact-filled reconstructions -- appearing to be related with too many poorly contacting electrodes. The iPhone scanning results in roughly 3.4 mm electrode accuracy (compared to a commercial photogrammetry system) with on average 203 of the 256 electrodes labeled. [ABSTRACT FROM AUTHOR]
