26 June 1998 Digitized mammogram standardization for display and CAD

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.
