A directional total variation minimization algorithm for isotropic resolution in digital breast tomosynthesis
Emil Y. Sidky, Xiangyi Wu, Xiaoyu Duan +9
An optimization-based image reconstruction algorithm is developed for contrast enhanced digital breast tomosynthesis (DBT) using dual-energy scanning. The algorithm minimizes direc…
4D-image reconstruction directly from limited-angular-range data in continuous-wave electron paramagnetic resonance imaging
Zheng Zhang, Boris Epel, Buxin Chen +5
Objective: We investigate and develop optimization-based algorithms for accurate reconstruction of four-dimensional (4D)-spectral-spatial (SS) images directly from data collected o…
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…
Directional-TV Algorithm for Image Reconstruction from Limited-Angular-Range Data
Zheng Zhang, Buxin Chen, Dan Xia +2
Investigation of image reconstruction from data collected over a limited angular range in X-ray CT remains a topic of active research because it may yield insight into the developm…
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…
