Compared with commonly used analytical reconstruction methods, the frequency-domain finite element method (FEM) based approach has proven to be an accurate and flexible algorithm for photoacoustic tomography. However, FEM-based is computationally demanding, especially three-dimensional cases. To enhance algorithm's efficiency, in this work a parallel computational strategy implemented framework of using graphic-processing-unit frame named "compute unified device architecture." A series simulation experiments carried out test accuracy accelerating effect improved method. The results obtained indicate that calculation does not change algorithm, while its cost significantly reduced by factor 38.9 GTX 580 graphics card
