Currnetly, in Japan, plans are being developed for introducing mammography examinations as a breast cancer screeing procedure. The International Electrotechnical Commission(IEC)has an active role to in establishing standards for mammography. To prepare a draft of national standards for mammography units, and discuss the draft of the IEC standards, the Japan Industries Association of Radiation Apparatus(JIRA)established last year a new technical subcommittee(Subcommittee SC-2205). The subcommittee also supports the Japan Radiological Society Committee on "Making Guidelines for Mammography" in preparation of protocols for the performance of the mammography System and the establishment of quality control standards. In this sumposium, we introduce our proposals for the basic performance of the mammography units and quality control standards in mammographic screening.
