A large share of that, $100,000, went toward the purchase of a digital mammography unit at the Halifax Shopping Centre breast screening site.

The province is in the process of replacing film-based mammography at its breast screening clinics with full-field digital machines that are both quicker than traditional machines and provide more accurate results for women with dense breasts.

Another project funded by the Breast Cancer Foundation aims to use the more detailed information produced by digital mammography to develop a more accurate measure of breast density and how it relates to the risk of developing cancer.

Mohamed Abdolell of Dalhousie University¡¯s department of diagnostic radiology received about $45,000 for his two-year project.He said there's a well-established link between high breast density and breast cancer. But doctors relying on film-based mammography have to eyeball the two-dimensional images and slot the results into four broad categories of density.

Mr. Abdolell hopes to use the three-dimensional digital information to define a more precise measure of breast density on a scale running from zero to 100 per cent.

He would then develop a mathematical method to automatically grade mammograms. The results could then be further sorted according to breast cancer risk.
