Volume Cutting for Virtual Petrous Bone Surgery

Biomedical Paper Volume Cutting for Virtual Petrous Bone Surgery

Objectives: A profound knowledge of anatomy and surgical landmarks of the temporal bone is a basic necessity for any otologic surgeon. Since this knowledge, so far, is mostly taught by limited temporal bone drilling courses, our objective was to create a system for virtual petrous bone surgery, which allows the realistic simulation of specific laterobasal surgical approaches. A major requiremen...

Realistic haptic volume interaction for petrous bone surgery simulation

In this paper, a new approach for haptic volume interaction with high resolution voxelbased anatomic models is presented. The haptic rendering is based on a multi-point collision detection approach which provides realistic tool interaction with the models. Both haptics and graphics are rendered at sub-voxel resolution, which leads to a high level of detail and enables the exploration of the mod...

An integrated simulator for surgery of the petrous bone.

This paper describes work being undertaken as part of the IERAPSI (Integrated Environment for the Rehearsal and Panning of Surgical Intervention) project. The project is focussing on surgery for the petrous bone, and brings together a consortium of European clinicians and technology providers working in this field. The paper presents the results of a comprehensive user task analysis that has be...

Developing a virtual reality environment in petrous bone surgery: a state-of-the-art review.

Virtual modelling of the surgical anatomy of the petrous bone.

The surgical anatomy of the petrous bone is difficult to learn and to imagine due to the porous structure. Obviously the surgeon's training is based on cadaver dissections as we are still lacking good, versatile models of the temporal bone and its important structures. The clearly visible, rapid development of computer science provides us with new possibilities that should be immediately engage...
