Abstract

We present experimental evidence that the optical absorption coefficient images of heterogeneous media can be obtained with quantitative photoacoustic tomography (PAT). Photoacoustic images are obtained from a series of tissue-like phantom experiments using a finite element-based reconstruction algorithm coupled with a scanning photoacoustic imaging system. The experimental results show that optical absorption images can be quantitatively reconstructed when the photon diffusion model is coupled with the Helmholtz photoacoustic wave equation.
