Virtual trabecular bone models and their mechanical response

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2008
The study of the mechanical behaviour of trabecular bone has extensively employed micro-level finite element (μFE) models generated from images of real bone samples. It is now recognized that the key determinants of the mechanical behaviour of bone are related to its micro-architecture.

Bone Surgery Simulation With Virtual Reality

Volume 1: 23rd Computers and Information in Engineering Conference, Parts A and B, 2003
Precise bone preparation is a key element for the successful long-term fixation of orthopaedic implants. Initial stability leading to reduced micromotion and direct apposition of the bone against the implant are mainly responsible for proper load transfer and bone remodeling.

Virtual Temporal Bone Dissection Simulation

2000
We have developed a working prototype system for the virtual simulation of temporal bone dissection. The system offers a paradigm from traditional practices by integrating technological advances to provide a safer and more cost effective way to learn fundamental techniques used in temporal bone surgeries.

Parallelized collision detection with applications in virtual bone machining

Computer Methods and Programs in Biomedicine, 2020
Virtual reality surgery simulators have been proved effective for training in several surgical disciplines. Nevertheless, this technology is presently underutilized in orthopaedics, especially for bone machining procedures, due to the limited realism in haptic simulation of bone interactions.

Virtual bone drilling for dental implant surgery training

Proceedings of the 16th ACM Symposium on Virtual Reality Software and Technology, 2009
Mechanical removal of bone material is the most critical procedure during dental implant surgery because it can jeopardize patient safety in several ways such as damage in the mandibular canal and piercing of the maxillary sinus. With recognition of the effectiveness in virtual training, many simulators with haptic feedback have been proposed. Although

Application deployment in virtual networks using the X-Bone

Proceedings DARPA Active Networks Conference and Exposition, 2003
This paper describes a framework for application deployment within virtual networks using X-Bone. The framework supports deployment of arbitrary applications and allows users to configure the runtime environment by executing user-provided scripts instead of hard-coding application commands into the system.

Individual models for virtual bone drilling in mastoid surgery

Computer Aided Surgery, 2009
Segmented training cases for virtual simulation of bone-drilling interventions in middle ear surgery have proven to be helpful in learning about surgical anatomy of the temporal bone. The anatomy of the mastoid shows a high degree of variability, however, and the aim of this study was to evaluate whether individual virtual models could be created ...
