Enhanced imaging of microcalcifications in digital breast tomosynthesis through improved image‐reconstruction algorithms
Purpose: The authors develop a practical, iterative algorithm for image‐reconstruction in undersampled tomographic systems, such as digital breast tomosynthesis (DBT). Methods: The algorithm controls image regularity by minimizing the image total variation (TpV), a function that reduces to the total variation when or the image roughness when . Constraints on …
