The Katsevich image reconstruction algorithm is the first theoretically exact cone beam image reconstruction algorithm for a helical scanning path in computed tomography (CT). However, it requires much more computation and memory than other CT algorithms. Fortunately, there are many opportunities for coarse-grained parallelism using multiple threads and fine-grained parallelism using SIMD units that can be exploited by emerging multi- core processors. In this paper, we implemented and optimized… CONTINUE READING
