Fast and accurate voxel projection technique in free-form cone-beam geometry with application to algebraic reconstruction

2008 First International Symposium on Applied Sciences on Biomedical and Communication Technologies, 2008
A modification is introduced to an established ray-tracing technique for computing line integrals in a rectangular voxel lattice in a free-form cone-beam imaging geometry. The result is a fast and accurate technique for computing a digitally reconstructed radiograph (DRR), which can easily be extended to simultaneous algebraic reconstruction technique (
