Time to Compute Pseudo-CT Volume Using Different Implementations and Atlas Sizes
| Computational time | ||||
| Volumes in atlas | Matlab (d) | C (min) | C OpenMP (min) | GPU (min) |
| 5 | 11.44 | 119.91 ± 0.02 | 61.76 ± 0.09 | 4.43 ± 0.00 |
| 7 | 16.18 | 168.08 ± 0.04 | 74.34 ± 0.29 | 6.20 ± 0.00 |
| 10 | 26.89 | 240.11 ± 0.14 | 99.84 ± 0.13 | 8.86 ± 0.00 |
Data are mean ± SD (Matlab code was tested only once because of computational cost).
