Abstract
Combining CT representing bone structures and PET visualizing functional information reveals many advantages in the area of cancer diagnosis and treatment. Here, fully automatic registration is desired but very time-consuming when considering big datasets. We present a technique to register CT and PET datasets based on the "Mutual Information" criterion. To overcome the speed problem, we developed a new approach for the matching based on partial volumes introducing a "3D cross model".
