Compared with the traditionalFDKalgorithm, the two PI algorithms decrease the helical shadow.对PI-Original和PI-Slant算法，本文采用了对称通道投影弥补的方法解决了这两个算法本身由于忽略了浮点运算误差造成的投影损失问题，与传统FDK重建算法相比，PI方法更好地减少了螺旋扫描所产生的图像尾影。
Thispaper described these two parallelization methods of theFDKalgorithm. The results of our simulationson a small cluster system is reported.本文针对三维锥束CT 中常用的FDK算法,研究了按以上两种思路实现的不同并行化方法,并给出了在一个小的集群系统上的模拟实验结果。
However, you need to accept theFDKend-user License agreement first, and use them at your own risk, and with no guarantee of support.不过，您需要接受FDK最终用户协议，自己承担使用中的风险，并且没有技术支持方面的保证。
The first sub-result is calculated by applying theFDKalgorithm 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;
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 onFDKand 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%以上。
In the back-projection process of theFDKalgorithm,every voxel s project distribution in the detector have itself characteristics,This paper presents a new interpolation method.针对在FDK算法的反投影过程中,各个体素在探测器上投影分布的特点,本文提出一种新的插值方法。 |
