GPU-based iterative transmission reconstruction in 3D ultrasound computer tomography
We accelerate a ray-based 3D ultrasound CT reconstruction by GPU processing. By use-case optimized SpMV variants a speedup of one order of magnitude is obtained. We derive the optimal number of GPUs for reconstructions that do not fit on one GPU. A 3D-preview is reconstructed in 0.5 s, a high-resolution volume in 23 s.
