The objective of this proposal is to develop a digital mammographic imaging system with high contrast, good resolution, and low patient dose. A new technology, polycapillary optics, has been shown to produce clearer images by increasing contrast and resolution. A number of prototype systems are being studied borosilicate and leaded glass fibers, collimating and monolithic focusing lenses. A number of fibers have been measured and simulated in the energy range 10 8OkeV. Short lead glass optics seem promising for scatter rejection. A long focal length collimating lens has transmission close to 45 at mammographic energies. The monolithic focusing lens with focal distance is 50 cm has transmission of 2l at 20 keV.
