High Resolution and Sensitivity Digital X-Ray Imager for Mammography
Abstract
A digital x-ray imager with a full-size (8"x10") screen and high resolution (40(m) is being developed. By applying current engineering devices and practices, a low cost and noise imager is expected. A long-term goal is to incorporate the lower noise x-ray light valve (XLV) into the imager. We expect to achieve the same size, resolution and image quality as film/screen. During the third year the first generation imager design (6x6 array, without XLV) was finished and a prototype of the CCD electronics and digital signal processor was tested. The mosaic image reconstruction software was further refined and the reconstruction accuracy tested for various algorithms and applications. The circuit design, circuit board layout, and mechanical design for the full scale imager were completed. A 3x3 section with temporary lens was tested.
