Abstract

Photoacoustic tomography (PAT) - a rapidly emerging imaging technique - proves to have potential for biomedical in vivo imaging. We propose a fast algebraic reconstruction technique for PAT based on radial basis functions. We derive analytical descriptions of the action of the spherical Radon transform on several radial basis functions, enabling a memory efficient implementation of the reconstruction algorithm. We demonstrate the applicability of our method in numerical experiments on real and synthetic data.
