Investigations into Error Reduction Based FDK Algorithms

TANG Jie ZHANG Li,XING Yu-xiang,CHEN Zhi-qiang(Department of Engineering Physics,Tsinghua University,Beijing 100084,China)  
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 per-formance 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.
