As digitization of mammography progress, Japan Radiological Society(JRS)and Japanese Society of Radiological Technology(JSRT)have revised the mammography guideline for film-screen systems, including articles on printing digital data onto film, in 2004. It clarified the specifics on QA control. In the meantime, the guideline has been reviewed to prepare for the softcopy interpretation and clinical studies have been conducted. Due to the particularity of mammograms, the display performance required of mammographic image displays is much higher than those of general use displays. Though it may still fall short of film, the display performance has been greatly improved and more products in the market are rated well-acceptable, thanks to higher display resolution and technical developments of peripheral circuitry and firmware. In this paper, we would first like to discuss the latest technology and regulatory trends, including comparison between softcopy and film and between softcopy and CRT, and display accuracy. We would then like to introduce our newly developed 5M monochrome LCD ME 551i2 in this paper.
