Single-Pulse Dual-Energy Mammography Using a Binary Screen Coupled to Dual CCD Cameras
Abstract
This is the fourth annual report for this four-year grant, however a one-year no cost extension was requested and approved. The original goals of this grant (circa 1993) were based upon the use of dual CCD cameras for the digital mammographic acquisition. After studying the CCD detector, and in consideration of recent developments in detector technology, we have abandoned the original objectives for single x-ray pulse, dual detector mammography and are focussing on a dual x-ray pulse, single detector system approach. The primary motivation for this change was based on poor DQE results of the rear CCD detector system in the original sandwich design. Also, an amorphous silicon thin film transistor x-ray detector system became available in the principal investigator's laboratory as a result of other research agreements. This technology is available for this research at no cost to this grant. Monte Carlo studies have been completed which assess the dose to the breast at higher energies, and these data were necessary for the optimization studies now underway. Dual-energy mammography remains promising, especially with digital systems nearing the marketplace. The potential of the dual energy examination should be well understood at the end of this coming year.
