Using advanced simulation technology for cranial base tumor evaluation.

Skull base tumors are considered one of the most difficult pathologic entities to diagnose and treat. The physician is heavily dependent on imaging studies to determine the best form of treatment. As imaging technology becomes more advanced, the physician will need to be able to intuitively explore the complex data. Such intuitive exploration requires the use of high performance computer hardware and software. Issues related to this concept and a summary of current work in this area are presented.

A volumetric approach to virtual simulation of functional endoscopic sinus surgery.

Advanced display technologies have made the virtual exploration of relatively complex models feasible in many applications. Unfortunately, only a few human interfaces allow natural interaction with the environment. Moreover, in surgical applications, such realistic interaction requires real-time rendering of volumetric data-placing an overwhelming performance burden on the system. We report on a collaboration of an interdisciplinary group developing a virtual reality system that provides intuitive interaction with volume data by employing real-time volume rendering and force feedback (haptic) sensations. We describe our rendering methods and the haptic devices and explain its utility of this system in the real-world application of Endoscopic Sinus Surgery (ESS) simulation.
