Visualization of the Cortical Potential Field By Medical Imaging Data Fusion

. In this paper, we describe the visualization of the potential field on the scalp and on the cortical surface. The surfaces are derived from magnetic resonance imaging data and the potential fields are reconstructed as the solution to an inverse problem. The visualization tool is validated with clinical studies. 1 Introduction and Problem Background Visualization tools provide insight for users to deal with the abundance of information and data available in our information age. An important application of visualization is in medical imaging, where many imaging modalities have been developed for different organs and applications. Integration of different imaging modalities for the diagnostics of the human brain, for example, has the potential to improve neuroscientific tasks such as noninvasive localization of epileptic spikes and seizures. Among the many modalities available, electroencephalographic (EEG) data have the advantage of low cost, availability, and millisecondtime resoluti..
