Flow Visualization for Bioelectric Activity in Human Body

Standard techniques used to visualize the human bioelectric activity are typically restricted to depictions of scalar potentials or activation times. Hence they offer no explicit representation of the geometry of the current. We show in this paper that advanced flow visualization techniques can be successfully applied to this type of data. Applications to cardiovascular research and source reconstruction in the brain are presented that demonstrate the potential of this approach to yield new insight into biomedical data sets.
