1. A method of navigating between and localizing dedicated positions in mutually different medical images, comprising: providing an input interface for acquiring a first image of a breast in a first compression state and a second image of the breast in a second compression state; receiving a user input signal on a user interface for marking a first position in the first image; applying a shape prediction algorithm to predict a decompressed shape for the first and second image and for obtaining a rough coordinate transformation mapping the first position provided by a user in the first image into a corresponding second position in the second image; applying a CAD algorithm to the first and second breast images to detect anatomical structures of multiple classes; refining the rough coordinate transformation for mapping locations in the first image into the corresponding second position in the second image by processing and matching landmarks of corresponding classes; and localizing the second position in the second image based on the refined coordinate transformation, and thereby executing the method steps without explicitly registering the first and second images.
