Before revision:  This leads to improved registration performance on volumes with voxels of varying reliability, such as interpolated clinical scans . SparseVM registers 3D scans in under a second on the GPU, which is orders of magnitudes faster than the best performing clinical registration methods, while still achieving comparable accuracy.
After revision:  This leads to improved registration performance on volumes with voxels of varying reliability, such as interpolated clinical scans . SparseVM registers 3D scans in under a second on the GPU, which is over 1000x faster than the best performing clinical registration methods, while still achieving comparable accuracy.
