Dual-energy CT imaging with limited-angular-range data
Buxin Chen, Zheng Zhang, Dan Xia +2
In dual-energy computed tomography (DECT), low- and high- kVp data are collected often over a full-angular range (FAR) of . While there exists strong interest in DECT wi…

Non-convex primal-dual algorithm for image reconstruction in spectral CT
Buxin Chen, Zheng Zhang, Dan Xia +2
The work seeks to develop an algorithm for image reconstruction by directly inverting the non-linear data model in spectral CT. Using the non-linear data model, we formulate the im…
