Multiscale bilateral filtering for improving image quality in digital breast tomosynthesis

Purpose: Detection of subtle microcalcifications in digital breast tomosynthesis (DBT) is a challenging task because of the large, noisy DBT volume. It is important to enhance the contrast‐to‐noise ratio (CNR) of microcalcifications in DBT reconstruction. Most regularization methods depend on local...
