Abstract:
Our goal is to automatically extracthe surface of the intra-cranial cavity (ICC) from a magnetic resonance scan of a patient’s head. The structures comprising the ICC can vary considerably in shape and in size from one patiento another, making this segmentation task challenging to automate. We discuss the limitations of existing energy minimizing techniques like snakes and balloons with respect to this application, and introduce a radial force based method which has produced promising results.
