Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Laser Doppler imaging for intraoperative human brain mapping

Michaël Unser, Dimitri Nestor Alice Van De Ville, Theo Lasser, Marcel Leutenegger, Rainer Leitgeb, Erica Martin-Williams

The identification and accurate location of centers of brain activity are vital both in neuro-surgery and brain research. This study aimed to provide a non-invasive, non-contact, accurate, rapid and user-friendly means of producing functional images intrao ...

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 ...

Nonrigid medical image registration

Francisco Javier Sanchez Castro

Over the last two decades medical image processing has become a fundamental tool in medicine, and brain imaging is a paradigm thereof. The fast development of the imaging acquisition techniques allows medical staff to dispose of a variety of data coming fr ...

Development of a Microsurgery Training System

Hannes Bleuler, Etienne Burdet, Fei Wang

Surgeons require significant training to acquire sufficient dexterity and hand-eye coordination to manipulate objects skilfully under the microscope. This paper presents a computer-based real-time simulation of microsurgery as well as the hardware setup. I ...

Image-guided surgical microscope with mounted minitracker

Gaëtan Marti, Jaime Garcia Giraldez

A new image-guided microscope using augmented reality overlays has been developed. Unlike other systems, the novelty of our design consists in mounting a precise mini and low-cost tracker directly on the microscope to track the motion of the surgical tools ...

Image-guided Surgical Microscope

Gaëtan Marti

We present an image-guided surgical microscope system using augmented reality image overlays added onto one of the views of the operating microscope. With this system, segmented objects, outlines of risk regions, access pathways or 3D objects, previously e ...

Design of a haptic forceps for microsurgery training

Hannes Bleuler, Roger Gassert, Etienne Burdet, Fei Wang

While feedback of the grasping force is necessary to manipulate objects skillfully, most Virtual Reality systems do not provide such feedback. Grasping an object is often reduced to pushing a button on the interface. This paper presents the design and real ...

Eye-guided laser surgery

Klaus Benedikt Schönenberger

The application of lasers in microsurgery and in particular in neurosurgery offers many advantages such as, e.g., hemostasis, no-touch (i.e. aseptic) procedures, and pinpoint accuracy. However, these advantages can often not be fully exploited since adequa ...

Assessment of MR image deformation for stereotactic neurosurgery using a tagging sequence

David Lyndon Emsley

A tagging sequence is used to assess MR image deformations before a stereotactic neurosurgical procedure, in a test model and in two patients. This pulse sequence superimposes narrow parallel orthogonal tag lines on an image, which can be used as an intern ...
