Improving depth-resolution, in-plane contrast, and reducing non-uniformity artifacts for wide-angle DBT
Emil Y. Sidky, Adrian A. Sanchez, John Paul Phillips +4
Purpose: This work aims to develop an image reconstruction algorithm for wide-angle digital breast tomosynthesis (DBT) that has improved depth resolution and in-plane contrast whil…
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…
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…
