Outline of Final Research Achievements

The data size and the image processing of digital mammography differ from each other equipment, and are not unified. Therefore, in Japanese mammographic screening, introduction of soft copy interpretation is behind. This research was done for the purpose of developing the system for which every mammogram can display optimally. The research program document was submitted to the Ethics Committee of each institution in collection, and after recognition, mammograms are anonymized and collected as uncoupling data. After, we study the histogram analysis of each digital mammogram, it asked for the optimal main concentration of an image display, the gamma coefficient, the frequency emphasis function, etc. The digital mammography viewer with this software was developed, and that clinical evaluation was performed. As compared with the original soft-copy image, our soft-copy images can be displayed on 5M monitor without picture deterioration was checked.
