Abstract
Mammography is the first choice for diagnosis of breast disease, and it has been playing an important role in both screening and diagnostic examination. Recently, digital mammography systems, such as Full Field Digital Mammography (FFDM) and Computed Radiography (CR), have been developed and acquired widely in Japan. In this paper, we discuss the digital mammography system, soft copy reading, a new application (computer-aided detection system) and a new image acquisition system (tomosynthesis).
