A virtual liver, a better chance of life
Date:1/8/2010

EUREKA project E! 3184 Odysseus has developed systems to construct 3D images of individual patients' livers, with their tumours or other pathologies, from MRI or CT-scans. The reconstructions can be transmitted to external experts in any location, for consultation in real time just before surgery. Collaborative decisions can be made and optimal therapy planned with the best possible diagnostic support, before real surgery is attempted. Simulation of laparoscopic and robotic surgery, with tissue resistance, can be used either to practise the exact surgery proposed for an individual patient, or also for training several surgeons simultaneously.

Medical imaging of organs and tissues has contributed greatly to diagnosis and therapy planning, especially in the treatment of cancers, which are the major cause of deaths worldwide. However the 2D scanning images possible until now have been difficult to interpret, and it has not been possible to consult others who are not present in person. The EUREKA project Odysseus has developed software for 3D-imaging of the blood vessels of a patient's liver which has materially advanced medical understanding of how the liver is segmented. Until now, liver surgery has been based on the anatomy classically described by Couinaud in 1957. But the 3D modelling has shown that up to 50% of patients have a significantly different liver structure from the Couinaud description. "Thanks to the 3D modelling," says Professor Luc Soler of the Institut de Recherche pour les Cancers de l'Appareil Digestif (IRCAD), "the future of liver surgery has gained more precision through accurate definition of the liver's blood vessels."

Multiple skills

But this is only one part of the achievements of Odysseus. The project brought together partners with expertise in tumour detection, endoscopy, virtual simulation and specialised software for image transmission and reconstruction at a distance, in real time. The products d
