Unfortunately, up to now, there is no an efficient algorithm to deal with the iterative reconstruction algorithm, especially from fan-scanned projections.

对于迭代重建，目前尚无很好地解决该问题的算法，特别是对扇束投影重建问题。

Methods the CF iterative algorithm was applied to update the noisy detected emission sinogram data using the latest reconstructed image in the iterative process of PET reconstruction.

在PET重建的迭代过程中，此种负反馈迭代算法利用最近的一次重建图像来更新有噪声的探测到的发射正弦图数据。
