The work entitled “Surgery Training, Planning and Guidance using the SOFA Framework” has been awarded with a prize of the Dirk Bartz Medical Prize for Visual Computing in Medicine 2015. I wrote this paper with other SOFA user to demonstrate the potential and flexibility of the SOFA platform. This will be published in the Short and Medical Prize paper proceedings of EuroGraphics 2015.

I recently got accepted at the Computed Assisted Radiology and Surgery (CARS) conference 2015 for an oral presentation. CARS is a growing conference focusing on advanced medical imagingcomputer aided diagnosismedical simulation and robotics. The conference will take place in Barcelona from the 24th until the 27th of June 2015. See you there !

Internship available : Numerical Simulation for Cryotherapy

 

  • Research Team: SHACRA
  • Location: Strasbourg, IHU
  • Supervisor HDR: Stéphane Cotin
  • Co-supervisor: Hugo Talbot

 

Description

In our research team SHACRA, we develop interactive simulations targeting the training of medical students, pre-operative planning or per-operative guidance for surgeons. These simulations model the physiological behavior of the human body.

Within our partnership with the IHU Strasbourg, we develop innovative tools for interventional radiologists. The interventional radiology is the medical field treating diseases using different type of imaging (Xray, MRI…). We are more precisely focusing on the cryoablation procedure. This methods consists in inserting several cryo-needles inside the tumor, decompressing a gaz (argon) to freeze the tumor until cellular death (apoptosis). When the tumor is large, several needles must be used but the planning of the procedure requires a lot of experience.

We therefore develop a planification tool to better anticipate the effect of the cryo-needles before the operation. This represents a real challenge and would greatly help surgeons.

Objectives

  • Development of an interactive tool allowing to optimize the placement of needles in a 3D environment
  • Labelization/segmentation of the blood vessels in CT scans. Tools are already available in our simulation platform SOFA
  • A part of the internship will involve experiments in order to compare results with experimental data

 

This internship is located in Strasbourg, at IHU and assumes a collaboration with the NHC hospital in Strasbourg

Do not hesitate to contact me for any further details !
See you in Strasbourg !

Here I am !

After three and a half year of research, I defended my Ph.D. on Thursday the 10th of July at 1p.m.
The presentation took place at IRCICA in Lille.

And after two and a half hours of presentation, demo and questions, I finally got my Ph.D. with the “very honorable” mention ! Thanks to all the people I have been working with ! More especially to both teams SHACRA (Lille) and ASCLEPIOS (Sophia-Antipolis) !

During the NextMed 2014 event, I presented the first work done around cryoablation simulation. The presentation was entitled “Interactive Simulation for Cryotherapy Planning”.

In this talk, I presented a new planning framework for cryotherapy, compatible with the requirements set by interventional radiologists. Using contact-less technology, virtual cryoprobes can be interactively positioned in a sterile environment. Based on a fast yet accurate GPU implementation, the resulting iceball is computed in less that 30 seconds, outperforming previous work. This framework therefore allows to significantly decrease the safety margin by taking into account the synergistic effect of multi-cryoprobes with computation times consistent with clinical application while preserving accuracy. In this context, our numerical strategies, such as the choice of GPU computing or grid-based finite element approach, prove to be relevant.

The 10th Workshop on Virtual Reality Interaction and Physical Simulation VRIPHYS 2013 was hosted and organized by INRIA-Lille North Europe and the University of Lille 1.The VRIPHYS conference took place on November 27-29. It was organized in cooperation with Eurographics. This year, we decided to propose a tutorial/workshop dedicated to SOFA-users, which preceded the VRIPHYS conference on the November 27. More information about both events is available here.

This experience as member of the organization committee was time consuming but very interesting !
