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…
