An R&D-100 Award for a New Mammography System
AUGUST 27, 2007
A 2007 R&D 100 Award has been garnered by the Ultra-High-Resolution Mammography System (UHRMS) that equips doctors with a low-cost, high-quality alternative to digital radiography (currently the most popular mammographic technology at leading hospitals). The new mammography system was developed thanks in part to research carried out at the X-ray Operations and Research 2-BM beamline at the Argonne Advanced Photon Source. UHRMS represents a form of computed radiographic technology that replaces traditional x-ray film with a glass-ceramic imaging plate made of fluorochlorozirconate (FCZ), which then can be scanned, with the resulting data fed into a computer and digitized.
The Ultra-High Resolution Mammography System offers several notable improvements over common x-ray films and scintillating screens, including reusability, wide dynamic range, and direct digitization.
The developers/researchers are Argonne scientist Jacqueline Anne Johnson, SUNY-Stony Brook Research Assistant Professor Anthony R. Lubinsky, and University of Paderborn ( Germany ) Scientific Employee Stefan Schweizer.
As noted in their 2007 paper, "A Glass-Ceramic Plate for Mammography," published in the Journal of the American Chemical Society, the researchers used beamline 2-BM to characterize the new fluorochlorozirconate image plates. They further note that, “The materials show the potential for superior resolution to existing polycrystalline X-ray imaging systems, and they provide high X-ray conversion efficiency.”
