Paper Abstract

We report a universal back-projection formula for three-dimensional photoacoustic computed tomography in three types of imaging geometries: planar, spherical, and cylindrical surfaces. A solid-angle weighting factor is introduced in the back-projection formula to compensate for the variations of detection views. Numerical simulation demonstrates the performance of the algorithm.
