Abstract

Volume data reconstruction from cone-beam projections can be time consuming, typically reconstructing parallel axial slices. We present a system for performing fast, arbitrary-orientation CT slice reconstruction using commodity graphics processing units (GPUs). For 1024x1024 voxel slice reconstruction we have achieved a 89-fold performance improvement over a CPU implementation with comparable image quality.
