Statistical Image Reconstruction Using Mixed Poisson-Gaussian Noise Model for X-Ray CT
Qiaoqiao Ding, Yong Long, Xiaoqun Zhang +1
Statistical image reconstruction (SIR) methods for X-ray CT produce high-quality and accurate images, while greatly reducing patient exposure to radiation. When further reducing X-…

Image-domain multi-material decomposition for dual-energy CT based on correlation and sparsity of material images
Qiaoqiao Ding, Tianye Niu, Xiaoqun Zhang +1
Dual energy CT (DECT) enhances tissue characterization because it can produce images of basis materials such as soft-tissue and bone. DECT is of great interest in applications to m…
