Using the PhysX engine for physics-based virtual surgery with force feedback.
30 Aug 2009 BACKGROUND: The development of modern surgical simulators is highly challenging, as they must support complex simulation environments. The demand for higher realism in such simulators has driven researchers to adopt physics-based models, which are ...

Graphic and haptic modelling of the oesophagus for VR-based medical simulation.
30 Aug 2009 BACKGROUND: Medical simulators with vision and haptic feedback have been applied to many medical procedures in recent years, due to their safe and repetitive nature for training. Among the many technical components of the simulators, realistic and ...

A laboratory training and evaluation technique for computer-aided oral implant surgery.
30 Aug 2009 BACKGROUND: Navigated oral implant surgery requires knowledge and skills in computed tomography (CT) imaging, three-dimensional (3D) planning, and use of surgical navigation systems. To improve teaching and training, a laboratory training and ...

Reliability of pharmacokinetic parameters: small vs. medium-sized contrast agents.
30 Aug 2009 Current clinical applications of dynamic contrast-enhanced MRI (DCE-MRI) are based on the extravasation of relatively small contrast agents (SCAs). SCAs are considered disadvantageous, as they require high image sampling rates. Medium-sized contrast ...

k-t PCA: temporally constrained k-t BLAST reconstruction using principal component analysis.
30 Aug 2009 The k-t broad-use linear acquisition speed-up technique (BLAST) has become widespread for reducing image acquisition time in dynamic MRI. In its basic form k-t BLAST speeds up the data acquisition by undersampling k-space over time (referred to as ...

Bolus-tracking MRI with a simultaneous T1- and T2*-measurement.
30 Aug 2009 The aim of this study was to propose and evaluate a methodology to analyze simultaneously acquired T2*-weighted dynamic susceptibility contrast (DSC) MRI and T(1)-weighted dynamic contrast enhanced (DCE) MRI data. Two generalized models of ...

A simulation environment for diffusion weighted MR experiments in complex media.
30 Aug 2009 Simulations of diffusion in neural tissues have traditionally been limited to analytical solutions, to grid-based solvers, or to small-scale Monte Carlo simulations. None of these approaches has had the capability to simulate realistic complex ...
