Bioelectromagnetic Source Imaging

The importance of determining the functional status of the brain and the heart is self-evident, yet establishing a high-resolution spatio-temporal imaging modality remains a challenging research field. Innovative engineering advancements are essential to achieve such a goal. Brain activation is a spatio-temporally-distributed process. Recent advances in medical imaging technology, especially functional MRI, have greatly increased our ability to image brain functions with high spatial resolution. Electrophysiological recordings, on the other hand, offer millisecond temporal resolution in detecting and characterizing brain activity. The goal of this project is to develop bioelectromagnetic source imaging techniques to estimate the spatial distributions of bioelectric current and the electrical impedance distributions. The researchers’ approaches include the using the finite element method and various signal and image processing algorithms in order to estimate the functional status of the brain and heart from noninvasive measurements.
