Sparse-View X-Ray CT Reconstruction Using Prior with Learned Transform
Xuehang Zheng, Il Yong Chun, Zhipeng Li +2
A major challenge in X-ray computed tomography (CT) is reducing radiation dose while maintaining high quality of reconstructed images. To reduce the radiation dose, one can reduce…
Low Dose CT Image Reconstruction With Learned Sparsifying Transform
Xuehang Zheng, Zening Lu, Saiprasad Ravishankar +2
A major challenge in computed tomography (CT) is to reduce X-ray dose to a low or even ultra-low level while maintaining the high quality of reconstructed images. We propose a new…
PWLS-ULTRA: An Efficient Clustering and Learning-Based Approach for Low-Dose 3D CT Image Reconstruction
Xuehang Zheng, Saiprasad Ravishankar, Yong Long +1
The development of computed tomography (CT) image reconstruction methods that significantly reduce patient radiation exposure while maintaining high image quality is an important a…
