Abstract
Softcopy reading and CAD in mammography are both dependent upon the characteristics of the source of the digital data, either direct digital mammography or digitized screen-film mammography. In this work, a standardization is proposed based on geometric and intensity transformation that are discovered using a set of calibration images. A genetic algorithm is used to search for the best transformations. Results indicate that standardization for display can be achieved, but that CAD performance varies even after standardization: both sensitivity and false-positive rates appear to be reduced.
