Abstract

In the last several years most diagnostic imaging systems which were screen-film systems have been replaced with digital systems. However, mammography has not advanced as much toward digitization. The most important factor against digitization of mammography is detectability of micro-calcifications, which are essential in diagnosing breast cancer. Digital images have low special resolution relative to screen-film for the limited pixel sizes. Recently, with the aim of improving this situation, high resolution CR systems with a pixel size of 50μm (half the pixel size of conventional CR systems) and full field digital mammography systems with a flat-panel-detector (FPD) pixel size of 100μm have been developed and made commercially available. In this report, we describe the current state of digital imaging system development for mammography. The purpose of this report is to survey the future of digital mammography from comparisons of the results of the physical imaging properties and contrast-detail characteristics between digital mammography (FPD and high resolution CR) and screen-film (Min-R2000/Min-R2000) systems.
