Paper Abstract

Photoacoustic imaging is a promising technique combining high ultrasonic resolution and high optical contrast. However, quantification has proved rather challenging. In this paper, we present a non-iterative reconstruction strategy with multiple-optical-sources for reconstruction of absorption, scattering perturbations as well as the spatially varying Grüeneisen parameter from a known turbid background. We term this method the multiple-illumination photoacoustic tomography (MI-PAT). While numerical challenges still exist, we demonstrated that the linearized MI-PAT framework we propose has orders of magnitude improved condition number compared with Continuous-Wave Diffuse Optical Tomography (CW-DOT).
