A Deformable Finite Element Model for Breast Image Registration. An Application on MRI/PET Breast Images

But if, as happens increasingly, the image is ambiguous, if it is inconsistent, or, worse yet, if it flies in the face of our previous inferences, the mental model has to be forcibly revised. Large numbers of images may have to be reclassified, shuffled, changed again until a suitable integration is found. Sometimes whole groups of image-structures have to be torn down and rebuilt. In extreme cases, the basic shape of the whole model has to be drastically overhauled. Thus the mental model must be seen not as a static library of images, but as a living entity, tightly charged with energy and activity. It is not a "given" that we passively receive from outside. Rather, it is something we actively construct and reconstruct from moment to moment. Restlessly scanning the outer world with our senses, probing for information relevant to our needs and desires, we engage in a constant process of rearrangement and updating. At any given instant, innumerable images are decaying, dropping into the black immensity of the forgotten ...»
