In order to speed up CT scan and reconstruction,based on the analysis of the beam geometries relationship between parallel scan and fan-beam scan,the paper introduces a special scan model named short-scan which differ from traditional full-scan,and proposes an approach named parallel re-sorting to reconstructing images from short-scan fan-beam data.
传统扇束CT通常采用的是基于一周360°的全扫描方式,为了加快扫描速度,提高重建效率,在分析了扇束和平行束在几何上的关联性后,介绍一种不完全角度的扫描方式——短扫描,以及应用于该种扫描方式下的数据重排技术,并完成了算法的实现。
