摘要：
This paper presents an optimized implementation of the FDK algorithm on a single fixed-point TMS320C6455 digital signal processor(DSP).Software pipelining and proper configuration of the data transfer enables a 2563 volume to be reconstructed in about 42 seconds from 360 projections with very good accuracy.This implementation reveals the potential of modern high-performance DSPs in accelerating image reconstruction,especially when cost and power consumption are emphasized.
