| Abstract: | This paper proposes a new algorithm for reconstructing a binary section from projections. Based on the binary feature of the section, the algorithm uses pattern recognition to do reconstruction. The simulation results show that the new algorithm has the following advantages: it needs few projections, can detect fine defects and works well in the limited view condition. This paper describes the basic idea of implementing the new algorithm and presents a set of simulating results. |
