A software-based method for eliminating grid artifacts of a crisscrossed grid by mixed-norm and group-sparsity regularization in digital radiography
X-ray grids are typically used in clinical practice to improve image quality by decreasing the
effects of scatter radiation reaching the image detector. Recently, we developed a prototype …
