Moment-based cosh-Hilbert Inversion and Its Applications in Single-photon Emission Computed Tomography
Abstract
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 Noo2007, there is no exact and analytic inverse formula so far. Several approximated inversion algorithms of the CHT had been developed Noo2007You2007. In this paper, we proposed a new numerical moment-based inversion algorithm.
