High Resolution and Sensitivity Digital X-Ray Imager for Mammography.
Abstract
Two previously developed x-ray imager technologies, the x-ray light valve (XLV) and mosaic (segmented) digital imager are being combined into a larger area (8"xlO") screen with high resolution image (5Omicro) suitable for mammography. By applying current engineering devices and practices, a low cost and noise imager is expected. We expect to achieve the same size, resolution and image quality as film/screen. During the second year the overall imager design was finished and a prototype of the CCD electronics and digital signal processor was tested. The mosaic image reconstruction software was refined and the reconstruction accuracy tested for various algorithms and applications. An additional, intermediate goal of designing an imager with the array (6x6), but without the XLV, was added with the expectation that it can be produced earlier and at a lower cost than competitive imagers.
