The overall objective of this proposal is to develop a mammographic system with extremely high scatter rejection and dynamic range, good resolution and low patient dose. This will be accomplished by developing a direct x-ray detector interfaced with a capillary x-ray optic in an appropriately designed mammographic system. Measurements have been performed of transmission and absorbence of single capillaries. Preliminary measurements have been performed of pre-prototype optics. These measurements indicate that capillary x-ray optics should be suitable for enhancing contrast and performing beam shaping for matching with digital detectors. Simulation work on a collimating optic has shown good agreement with data and is progressing, which has allowed some design decisions for a suitable optic to be made. A prototype linear detector array has been constructed, along with readout electronics. A single pixel detector has been characterized.
