Computation time on the CPU (dotted lines) and GPU (full lines) for the two different PCs. The curves with 'o' correspond to the laptop (machine 1) and the curves with '+' to a standard PC (machine 2). The total time takes into account for calculating the complete 3D + t volume, which depends on the z sampling. The number of points in the z-axis is 30.
