- FDK算法FDK algorithm
- 该算法将单圆源轨扫描获得的投影通过FDK算法进行重建，将补全的缺失数据通过基于Grangeat公式精确重建算法重建，最后将两部分重建结果进行叠加得到最终的结果。The first sub-result is calculated by applying the FDK algorithm to the projection data acquired by a single circular orbit scan, the second sub-result is a correction received by applying SVFBP algorithm to the missing Radon data acquired by extrapolation, the final result is the sum of the two sub-results.
- 数据仿真实验结果表明 ,该算法在保持与传统FDK算法有相同的计算复杂度的同时 ,重建图像的质量有了明显的提高 ,可以确保在较大的锥角范围内获得满意的重建图像 .Then,the rebinned oblique parallel projection data are pre-weighting filtered. Finally,the filtered projection data are backprojected to the final 3-D reconstructed image data. Theory and experimental results show that the algorithm has the same computational complexity as traditional FDK algorithm while the image quality can be improved in the reconstruction.
