Conclusion
In this paper, we described a method to compare CC or MLO, left and right, breast images of the same patient for false positive reduction. Particularly, the developed method computes a geometric transformation bringing the symmetry axis of the two mammogram to overlap; then, through suitable user defined landmarks it computes a scale transformation that takes into account the breast deformation of one of the view with respect the other.
The geometrical transformations returned by this method have been used to operate a false positives number reduction. Indeed, applying the same transformations to the ROI images, it is possible to compare them and then select only those that are not correlated.
In this paper are reported the results of the method by using CyclopusCAD® powered by Medicad S.r.l. (EXPO E - 572).
