| 英文摘要 | Multi-GPUs accelerated BPF algorithm is developed for improving computational efficiency. Three major acceleration techniques are introduced: (1) dividing reconstructed volume into subsets vertically which reduces the computational cost on the boundary term between parallel chords; (2) transposed method is used to avoid low efficiency of access in global memory which is caused by different chords selection; (3) optimized memory allocation scheme is adopted. Experimental data are used to evaluate the image quality and reconstruction time. It takes only 4.118 s to reconstruct a volume image of 512 x 512 x 512 with 360 projection data of 512 x 512 on dual NVIDIA Tesla C2070 cards. Added the time consuming on data read, transfer and storage part, the completereconstruction process could be finished in less than 9 s. In particular, BPF-based ROI-reconstruction for cone beam Ortho-CT shows promising applicationprospect. |
