Title: "Variable Anatomical Models for Surgical Training Simulators" 5.2001-10.2004 Abstract: In the past few years virtual reality based systems have been proposed and realized for many medical interventions. These simulators have the potential to provide training on a wide variety of pathologies. So far, realistic generation of anatomical variance and pathologies have not been treated as a specific issue. It has to be possible for a physician to generate an individual surgical scene for every training session. This Ph.D. thesis will explore how to generate such anatomical models for surgical simulators considering the natural variability of the healthy anatomy and seamlessly integrating a wide spectrum of different pathologies according to the specifications from physicians.
