Closed-loop control of compression paddle motion to reduce blurring in mammograms (2017)
Journal Article

Background: Since the introduction of full field digital mammography (FFDM) a large number of UK breast cancer screening centers have reported blurred images, which can be caused by movement at the compression paddle during image acquisition.
Purpos... Read More about Closed-loop control of compression paddle motion to reduce blurring in mammograms.
