Fluence Adaptation for Task-based Dose Optimization in X-ray Phase-Contrast Imaging
Chengpeng Wu, Yuxiang Xing, Li Zhang +4
Purpose: Grating-based imaging (GBI) and edge-illumination (EI) are two promising types of XPCI as the conventional x-ray sources can be directly utilized. For GBI and EI systems,…
An Analysis of Scatter Characteristics in X-ray CT Spectral Correction
Tao Zhang, Zhiqiang Chen, Hao Zhou +3
X-ray scatter remains a major physics challenge in volumetric computed tomography (CT), whose physical and statistical behaviors have been commonly leveraged in order to eliminate…
Truncated analytic moment analysis and its hybrid-field contrast in grating-based x-ray phase contrast imaging
Chengpeng Wu, Li Zhang, Xinbin Li +4
For grating-based x-ray phase contrast imaging (GPCI), a multi-order moment analysis (MMA) has been recently developed to obtain multiple contrasts from the ultra-small-angle x-ray…
Unsupervised Learnable Sinogram Inpainting Network (SIN) for Limited Angle CT reconstruction
Ji Zhao, Zhiqiang Chen, Li Zhang +1
In this paper, we propose a sinogram inpainting network (SIN) to solve limited-angle CT reconstruction problem, which is a very challenging ill-posed issue and of great interest fo…
