Paper Abstract

Quantitative photoacoustic microscopy (qPAT) is challenging. We present an algorithm which consecutively reconstructs absorption and scattering coefficient distributions with an iterative scheme in multiple-illumination photoacoustic tomography (MIPAT). In each iteration, the absorption distribution is estimated with the least-squares fixed-point iteration method. Then the diffusion coefficient is estimated with an updated version of optical fluence based on the previously modified absorption information. This procedure is repeated till an acceptable results is achieved. Simulation examples demonstrate the capability of this method in faithfully recovering the absorption and diffusion coeffient distributions, and fast convergence.
