Photoacoustic Imaging of Epilepsy

Abstract

This research is aimed at developing a new imaging approach, called Photoacoustic tomography (PAT) , for non-invasively tracking dynamical changes during seizure occurrence. The project will develop imaging hardware and software, and conduct phantom/in vivo experiments to achieve the proposed goals. During the second year of this project, we have completed the construction of the proposed array based PAT system, and calibrated and tested the system using extensive phantom experiments. We have also built an animal interface and successfully tested it for in vivo imaging of rat brain. We have implemented three novel schemes that can enhance our current reconstruction software. We have conducted phantom experiments that confirmed our software enhancement.
