In quality control (QC) procedures for mammography, the image quality of phantoms is assessed and scored. In this paper, a QC database including phantom images is proposed in order to record and evaluate QC data from many institutions. A trial was performed on a Power Macintosh using data obtained in 1991 and 1995 from selected institutions. Phantom images were analyzed basically by NIH Image, and contrast-to-noise ratio was measured for test materials contained in the phantom. Computerized analysis of images facilitated quantitative assessment and comparison of image quality.
QC information services will be offered to registered institutions in the form of QC reports in the near future. The reports will include computerized analysis of phantom images with chronological comparison and comparison with reference images of superior quality. This kind of service for a number of institutions will be conducted effectively through a centralized QC organization.
