Non-unique water and contrast agent solutions in dual-energy CT
JP Phillips, Emil Y. Sidky, Fatma Terzioglu +3
The goal of this work is to study occurrences of non-unique solutions in dual-energy CT (DECT) for objects containing water and a contrast agent. Previous studies of the Jacobian o…
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…
Enhancing signal detectability in learning-based CT reconstruction with a model observer inspired loss function
Megan Lantz, Emil Y. Sidky, Ingrid S. Reiser +2
Deep neural networks used for reconstructing sparse-view CT data are typically trained by minimizing a pixel-wise mean-squared error or similar loss function over a set of training…
