A task-parameterized probabilistic model with minimal intervention control

We present a task-parameterized probabilistic model encoding movements in the form of virtual spring-damper systems acting in multiple frames of reference. Each candidate coordinate system observes a set of demonstrations from its own perspective, by extra ...

Particle Imaging Velocimetry Evaluation of Intracranial Stents in Sidewall Aneurysm: Hemodynamic Transition Related to the Stent Design

Mohamed Farhat, Pierre Bouillot

We investigated the flow modifications induced by a large panel of commercial-off-the-shelf (COTS) intracranial stents in an idealized sidewall intracranial aneurysm (IA). Flow velocities in IA silicone model were assessed with and without stent implantati ...

Fast virtual deployment of self-expandable stents: Method and in vitro evaluation for intracranial aneurysmal stenting

Luca Augsburger, Daniel Ruefenacht

Introduction: Minimally invasive treatment approaches, like the implantation of percutaneous stents, are becoming more popular every day for the treatment of intracranial aneurysms. The outcome of such treatments is related to factors like vessel and aneur ...

Integrated active tracking detector for MRI-guided interventions

Giovanni Boero, Jens Anders, Paul Sangiorgio

We present a fully integrated detector suitable for active tracking of interventional devices in MR-guided interventions. The single-chip microsystem consists of a detection coil, a tuning capacitor, an intermediate frequency downconversion receiver, and a ...

The riddle of style changes in the visual arts after interference with the right brain

Olaf Blanke, Isabella Maria Pasqualini

We here analyze the paintings and films of several visual artists, who suffered from a well-defined neuropsychological deficit, visuo-spatial hemineglect, following vascular stroke to the right brain. In our analysis we focus in particular on the oeuvre of ...

Intracranial Stents Being Modeled as a Porous Medium: Flow Simulation in Stented Cerebral Aneurysms

Nikolaos Stergiopoulos, Philippe Reymond, Luca Augsburger

Intracranial aneurysms may be treated by flow diverters, alternatively to stents and coils combination. Numerical simulation allows the assessment of the complex nature of aneurismal flow. Endovascular devices present a rather dense and fine strut network, ...

Effect of Flow Diversion Treatment on Very Small Ruptured Aneurysms

Luca Augsburger, Daniel Ruefenacht

BACKGROUND: Ruptured aneurysms of < 2 mm are not amenable to endovascular coiling and therefore pose a significant treatment challenge. ...

VR simulation of interventional radiology and microsurgery

Fei Wang

Currently trainees typically learn surgery techniques directly on mocks, animals or cadavers. For safety, cost and ethics reasons, one cannot try all possible strategies to achieve efficient learning. Virtual Reality (VR) based surgery training systems int ...
