基于FDK算法减小误差的研究
Investigations into Error Reduction Based FDK Algorithms
摘要
Abstract
In this paper, we describe the relationship between the reconstruction error and the locus radius. Based on this relationship we fomulate our new algorithm. Numerical simulations are done to evaluate its performance and show that the new algorithm can get more accurate reconstruction than algorithms of the same kind. Finally, we discuss the shortcomings of this kind of algorithms.关键词
