Seminar: Mathematics of Photoacoustic Tomography (22/12)
Speaker: Linh Nguyen, University of Idaho

Talk Title: Mathematics of Photoacoustic Tomography

Date: Friday December 22, 2017, 10am; Room F207.

Abstract:  Photoacoustic tomography (PAT) is a hybrid method of imaging. It combines the high contrast of optical imaging and high resolution of ultrasound imaging. A short pulse of laser light is scanned through the biological object of interest. The photoelastic effect produces an ultrasound pressure propagating throughout the space, which is measured by transducers located on an observation surface. The goal of PAT is to find the initial pressure inside the object, since it contains helpful information of the object.

The mathematical model for PAT is an inverse source problem for the wave equation. In this talk, we will discuss several methods for solving this inverse problem.
