Assessment of prior image induced nonlocal means regularization for low‐dose CT reconstruction: Change in anatomy

PURPOSE: Repeated computed tomography (CT) scans are prescribed for some clinical applications such as lung nodule surveillance. Several studies have demonstrated that incorporating a high‐quality prior image into the reconstruction of subsequent low‐dose CT (LDCT) acquisitions can either improve im...
