Direct radiography (DR) for conventional x-ray medical imaging application

Abstract

This paper introduces a new medical X-ray diagnostic imaging method: direct radiography (DR), which will resolve digitalization problem of conventional X-ray medical imaging, and may replace film imaging in the future. In our developed DR system, a high resolution amorphous Silicon (a-Si) image sensor is used which can acquire 1920*1536*12bits image in 1.6 seconds in its fastest imaging speed. The software of the system including DR image acquisition workstation and DR image post-process workstation can not only acquire, correct and store the images, but also can manage the DR images in network database. In the paper, the mechanism of DR imaging, the composition of the developed DR system, the advantages of DR imaging over traditional X-ray medical imaging are described, and DR imaging results of the developed system are shown at last.
