| Abstract: | Many changes have taken place in CT technology since it was invented. These changes not only appear in computer, detector and X ray technology but also in image reconstruction algorithm. A new kind of CT image reconstruction algorithm named Intermediate Function Algorithm is presented in this paper. This algorithm can be used both in fan-beam and cone-beam scan. The aim of the research is to find an effective reconstruction algorithm which can be used in cone-beam CT in the future. |
