A volumetric reconstruction algorithm named FT-FDK (flat-panel based tent FDK algorithm) is presented based on the ideas of Grasss T-FDK algorithm.
针对锥顶轨迹为单圆的锥形束体积重建问题，提出了一种基于平板检测器的T FDK算法。
The main reason is the radon space data of scanned object is not complete, which will result in the image artifacts when using FDK algorithm to reconstruct with moderate or large cone angles.
本文分析FDK算法在中大锥角时重建产生伪影的主要原因是投影数据不完全，被扫描物体雷当空间数据缺失。
