Abstract：

Digitally　Reconstructed　Radiograph　has　been　widely　used　in　2D-3D　image　registration.　This　paper　adopted　an　improved　method　which　optimizes　the　parallelization　on　GPU　to　accelerate　DRR　generation.　A　cubic　window　is　proposed　to　preprocess　the　object　data,　which　helps　accelerate　the　DRR　generation.　According　to　the　Cuda-based　experimental　results,　the　improvement　is　quite　obvious　and　the　image　quality　is　acceptable.　©　2012　IEEE.
