Sparse-view x-ray CT reconstruction via total generalized variation regularization.
Shanzhou Niu,Yang Gao,Zhaoying Bian,Jing Huang,Wufan Chen,Gaohang Yu,Zhengrong Liang,Jianhua Ma +7 more
TL;DR: Experimental results show that the present PWLS-TGV method can achieve images with several noticeable gains over the original TV-based method in terms of accuracy and resolution properties.
Journal ArticleDOI
A Simple Low-Dose X-Ray CT Simulation From High-Dose Scan
Dong Zeng,Jing Huang,Zhaoying Bian,Shanzhou Niu,Hua Zhang,Qianjin Feng,Zhengrong Liang,Jianhua Ma +7 more
TL;DR: Experimental results demonstrated that the present low-dose CT simulation strategy can generate accurate low- dose CT sinogram data from high-dose scans in terms of qualitative and quantitative measurements.
Journal ArticleDOI
Spectral CT Image Restoration via an Average Image-Induced Nonlocal Means Filter
Dong Zeng,Jing Huang,Hua Zhang,Zhaoying Bian,Shanzhou Niu,Zhang Zhang,Qianjin Feng,Wufan Chen,Jianhua Ma +8 more
TL;DR: The proposed average image-induced nonlocal means (aviNLM) filter has useful potential for radiation dose reduction by lowering the mAs in SCT imaging, and it may be useful for some other clinical applications, such as in myocardial perfusion imaging and radiotherapy.
Journal ArticleDOI
Convolutional Sparse Coding for Compressed Sensing CT Reconstruction
Peng Bao,Wenjun Xia,Kang Yang,Weiyan Chen,Mianyi Chen,Yan Xi,Shanzhou Niu,Jiliu Zhou,He Zhang,Huaiqiang Sun,Zhangyang Wang,Yi Zhang +11 more
TL;DR: Wang et al. as mentioned in this paper explored the potential of convolutional sparse coding (CSC) in sparse-view computed tomography (CT) reconstruction, without the necessity of dividing the image into overlapped patches in DL-based methods.
Journal ArticleDOI
Iterative Image Reconstruction for Sparse-View CT Using Normal-Dose Image Induced Total Variation Prior
Jing Huang,Yunwan Zhang,Jianhua Ma,Dong Zeng,Zhaoying Bian,Shanzhou Niu,Qianjin Feng,Zhengrong Liang,Wufan Chen +8 more
TL;DR: Experimental results show that the present PWLS-ndiTV approach for sparse-view CT image reconstruction can achieve noticeable gains over the existing similar approaches in terms of noise reduction, resolution-noise tradeoff, and low-contrast object detection.
