SBIR TOPIC 252 - NANOPHASE GLASS CERAMIC X-RAY IMAGING MATERIALS

This project is directed towards improving the quality and efficacy of mammography imaging technologies as a tool to identify early-stage cancer and so improve the prospects for full recovery of the patient. Computed radiography (CR) has largely displaced screen/film technology in clinical use. Recent advances in materials for CR image storage result in the need to produce nanophase glass ceramic transparent storage phosphor plates on a commercial scale. The perfection and subsequent production of the optical quality plates that are the heart of the x-ray sensors is the subject of this proposal. The research will involve: (i) systematic development of methods to produce the glass plates, (ii) optimization of heat treatment methods to produce the nanophase glass ceramic, (iii) characterization of the product, and (iv) development of the process map for production of optical quality material. The outcome of the research will be a detailed methodology for production of the plates and intellectual property that will enable successful commercial development of the technology. The products that will result from this research are high value-add materials that can serve established markets in advanced medical imaging and potentially access emerging markets in security technology and materials inspection.
