The present study examined the performance of a surgical procedure under simulated combat conditions. Eleven residents performed a cricothyroidotomy on a mannequin-based simulator in a fully immersive virtual environment running a combat simulation with a virtual sniper under both day and night...
Instruments and procedures continue to become more complex and challenging, but the display environments to which these technologies are connected have not kept pace. Display real-estate (the size and resolution of the display), the configurability of the display, and the ability for display...
Intra-operative navigation in which the target position is provided to assist an intuitive understanding of the surgical field has been studied and applied in many clinical areas. Position measurement of a surgical field is usually performed with a magnetic sensor, a marker type optical position...
The possibility of mass terrorism has become increasingly apparent. Accurate and relevant teaching tools are needed for healthcare givers and emergency personnel of all experience. We describe one of these tools, BODY Simulation, and its use in training caregivers to respond to chemical...
The Virtual Soldier Project endeavors to represent the baseline physiology and anatomy of a soldier using disparate but linked digital data types (http://www.virtualsoldier.net). Processing these data for storage, transmission and encryption requires different capabilities than are typical in a...
In this paper we present a technique for the modelling of realistic collisions between arbitrary rigid surgical tools and deformable geometry that is independent of the resolution of colliding objects. We use a spatial hash table to provide an efficient narrow-phase collision detection and...
Clinically relevant segmentation often incorporates physician insight in the segmentation process (eg. overestimation of tumors). This is a primary reason in the continued use of per-slice based segmentation approaches. Segmenting structures directly by interacting with a volume space provides...
Virtual Reality has been used for clinical application for about 10 years and has proved to be an effective tool for treating various disorders. In this paper, we want to share our experience in building a 3D, motion tracked, immersive VR system for pain treatment and biofeedback research.
In the automotive, telecommunication, and aerospace industries, modeling and simulation are used to understand the behavior and outcomes of a new design well before production begins, thereby avoiding costly failures. In the pharmaceutical industry, failures are not typically identified until a...
The aim of this study is development a prototype computational model of the pig heart that can be used to predict physiological responses to a penetrating wound injury. The pig has been chosen for this model studies because it shares many anatomical similarities with humans. Three-dimensional...
