A decomposition model with an iterative solving framework is proposed for use in MeV dual
energy computed tomography (DECT). The decomposition model can deal with a broad …

Dual-energy computed tomography (CT) is to reconstruct images of an object from two
projection datasets generated from two distinct x-ray source energy spectra. It can provide …

Penalized weight-least squares (PWLS) with basis material priors is a promising way to
achieve high quality material decompositions for Dual-energy CT (DECT). This paper …

BACKGROUND: High dose efficiency of photon counting detector based spectral CT (PCD-
SCT) and its value in some clinical diagnosis have been well acknowledged. However, it …

Dual-energy computed tomography (DECT) is a new and rapidly developing imaging
