Abstract

Mammography X-ray equipment uses the radiographic grid in order to remove the scatter radiation and to improve image contrast. The gridlines, such as striped lines, appear on the film and the gridlines are considered that diagnostic information may be impaired as an artifact. In this study, we developed the image processing technique which eliminated gridlines on films using digital image processing. We exposed the phantom, improved the gridlines image and detected the ripple components of the gridlines image. We could eliminate the gridlines from the calcifications image by using the ripple components of the gridlines image. By using digital image processing techniques, we could eliminate gridlines and extract the region of calcification. It was suggested that the accuracy of the mammographic diagnosis could be improved.
