Moreover, as will be discussed subsequently, advancements in iterative reconstruction methods for ct should result in further reductions in radiation exposure.

此外，随后将要讨论的，迭代重建方法的进步对于CT将进一步减少辐射。

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。
