Abstract: This paper studies a kind of using CUDA GPU parallel architecture to complete the FDK three- dimensional image reconstruction algorithm acceleration. In this paper,it analyzed the FDK algorithm parallelism characteristics,it designed for CUDA parallel method in weighted,filtering algorithm and the projection three phases. It realized the FDK acceleration. Through experiment compared with the algorithm implementation alone by CPU image reconstruction,it not only won more than 150 times speedup,bu... More
