High-resolution (35 micron) CCD-based film digitizer for mammography

摘要

Abstract: ation of screen film mammography is a necessary first step in the application of computer and communication technologies to breast cancer screening. A Georgetown University Medical Center team working together with DBA Systems, Inc. has been testing a CCD camera based film digitizer with a focal spot size of 35 microns. It is anticipated that this high resolution digitizer will assist in the development of a clinically acceptable digital mammography system for the purpose of digital feature analysis, transmission and storage.!0
