This past year we have been working on a wide variety of different research topics, where each relates to the global objective of this proposal but the individual projects are only loosely related to each other. The projects that are reported here are 1 x-ray spectral measurements, 2 novel screen evaluation, 3 analytical screen comparisons, 4 evaluation of attenuation coefficient data, 5 the development of a sine wave test pattern approach to measuring the MTF, 6 development of an image registration algorithm, 7 calculation of breast density from digital mammograms, and 8 mechanical fabrication of the digital mammography system. Progress in each of these projects has been substantial, and five manuscripts have been or will be shortly submitted covering these topics. Here we report, in vignette format, representative examples of the results of each of the projects. With these parallel efforts completed or close to completion depending on which project and the groundwork laid, in the upcoming year we can turn our focus towards putting together the actual dual energy mammography system, testing it, and evaluating its potential. We look forward to these continuing efforts with enthusiasm and optimism that dual energy mammography may be a realistic tool in the diagnostic work-up for breast cancer.
