Enhanced sparse view CT reconstruction using ordered subset expectation maximization and asymptotic non-local means algorithms

This study proposes the Ordered Subset Expectation Maximization–Asymptotic Non-local Means (OSEM-ANLM) algorithm for sparse-view Computed Tomography (CT) reconstruction under limited-data conditions and evaluates its performance across different acquisition settings. The algorithms were evaluated using a digital phan...
