- The first sub-result is calculated by applying the FDK algorithm to the projection data acquired by a single circular orbit scan. 该重建算法由两部分重建结果叠加而成,第1部分结果首先采用FDK算法通过对单圆扫描的投影数据进行重建来获得;
- If you are on an unstable circular orbit, then a tiny burst on your maneuvering thrusters will send you into the black hole, or off into outer space. 如果你驾驶飞船在黄色区域中运动，你的发动机哪怕只做出一点微小的喷射，都会使你掉入黑洞中，或是把你甩到外面的绿色区域中去。
- Anlysis shows that the scan field of view along the horizon can be improved no less than 80% compared with cone-beam 3D-CT based on FDK and circular orbit scan mode. 分析表明,其水平方向的有效扫描视野比基于FDK的圆轨道锥束扫描三维CT提高了80%25以上。
