One area that shows great promise is breast tomosynthesis. When we look at a mammogram, we're trying to examine three dimensional tissue in a two dimensional image. One feature may obscure view of another, hiding important information. This can lead to callbacks and more frequent biopsies.

Breast tomosynthesis takes a series of low dose exposures that are mathematically processed into a series of one millimeter slices, that show the tissue structure in three dimensions. The spatial ambiguity goes away and it becomes possible to see where a given feature really is. Early clinical trials suggest that breast tomosynthesis could revolutionize the way we think of mammography.
