Evaluation of a Digital Mosaic Mammography Imager

Abstract

Mosaic architecture based digital mammography is attractive since it offers an affordable and scaleable solution towards obtaining high resolution digital mammograms. Limitations on the clinical usability of the architecture are associated with the x-ray conversion screen utilized and to the methods employed to reconstruct the final digital mammogram. The x-ray conversion screen imposes limits on the efficiency of the optical conversion and the resolution of the finest resolvable detail. This can be addressed to an extent via use of specialized materials [1]. Reconstruction techniques, on the other hand, are likely to introduce artifacts in the final image. This can be addressed by employing complex reconstruction algorithms, which consequently may increase the time required to generate the final image.
