Scientific Context

We are principal contractor of an INRIA co-operative action on 3D Ultrasounds, in collaboration
 with EPIDAURE project in Sophia-Antipolis and ISA project in Nancy.

The goal of this project is to improve the exploitation of three-dimensional echographic images with an aim of assistance to the diagnosis and the therapeutic follow-up. It is about a new medical imaging  method, not too expensive, not very invasive for the patient and who allows to follow the movement of deformable anatomical structures in real time.

Research Directions

Within this framework our projects in progress go into two directions:

• on the one hand, the processing of a certain number of target pathologies starting from a 3D echographic imagery like the peripheral vascular imagery (e.g. for the carotid plaque) or like the perinatal imagery (trans-fontanelle imagery or orthopedic imagery for instance). This is done in collaboration with various university hospitals (Tours - Drs L. Pourcelot and F. Tranquart, Brest - Dr. Y. Bizais and Rennes - Dr. P. Darnaux) and local SME (ETIAM).

• in addition we work on the realization of an per-operative vision environment in neurosurgery allowing to visualize, in real time, the deformation of cerebral anatomical structures using a 3D echographic imagery and consequently to correct the presurgical planning made beforehand on the anatomical imagery (MRI) or even on functional (fMRI, MEG) data. This project is done in collaboration with the university hospital of Rennes (Dr. J.M. Scarabin) and the SIM laboratory at the faculty of medicine of Rennes.
