针对均匀衰减截断投影数据的单光子发射计算机断层扫描中的cosh-Hilbert变换反演问题,提出了一种基于矩的数值反演算法。

摘要:

cosh-Hilbert变换(CHT)的反演是均匀衰减截断投影数据的单光子发射计算机断层扫描中最关键的步骤之一。尽管CHT反演的唯一性已被证明,但至今尚无精确的解析反演公式。已有几种近似的CHT反演算法被开发出来。本文提出了一种新的基于矩的数值反演算法。

英文摘要:

The inversion of cosh-Hilbert transform (CHT) is one of the most crucial steps for single-photon emission computed tomography with uniform attenuation from truncated projection data. Although the uniqueness of the CHT inversion had been proved \cite{Noo2007}, there is no exact and analytic inverse formula so far. Several approximated inversion algorithms of the CHT had been developed \cite{Noo2007}\cite{You2007}. In this paper, we proposed a new numerical moment-based inversion algorithm.
