The study reports a reconstruction algorithm for three‑dimensional photoacoustic computed tomography. The algorithm uses a universal back‑projection formula applicable to planar, spherical, and cylindrical geometries, incorporating a solid‑angle weighting factor to correct for varying detection views and detailing its implementation. Numerical simulations demonstrate the algorithm’s performance.
We report results of a reconstruction algorithm for three-dimensional photoacoustic computed tomography. A universal back-projection formula is presented for 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. A method for implementing this algorithm is described. Numerical simulation is used to demonstrate the performance of the algorithm.
