  abstract =   "Endoscopy is an integral part of medical practice although
               the procedure is often unpleasant for the patient. Virtual
               endoscopy is a diagnosis tool which visualizes 3D image data
               sets to show a virtual view of the patient similar to the
               images generated by a traditional endoscopy. A

               endonasal pituitary adenoma surgery. This thesis describes a
               deformation engine extending the STEPS application to
               enhance the realism. The two main contributions are the
               development of the Divod ChainMail algorithm, an algorithm
               for direct volume deformation based on the Chain- Mail and
               Enhanced ChainMail algorithms, and the integration of the
               engine into the existing STEPS. We use a Constrained
               Particle System to directly model and manipulate the volume
               data instead of modeling objects extracted from the volume
               data. We further proposes a simple interface to ease
               integration and enforce reusability of the software
               components. This thesis describes our Divod ChainMail
               algorithm, the interface and integration details, and
               provides timing results. Finally, it offers a discussion of
               the presented methods pointing out possible improvements and
               further work.",
