The medical sciences have always been on the forefront of adapting technology to vital human needs. Visualization has become a key element in communicating and understanding medical information, and in enabling more complex health data to be tackled. At the same time, the advent of real-time visualization has ushered in a new generation of tools allowing delicate and high-precision surgical interactions that would otherwise be impossible.

In this session of Montreal ACM SIGGRAPH, we will get an overview of the state-of-the-art of medical visualization from a well known Montreal researcher, and witness ORTHOsoft's real-time surgical motion tracking system, NaviTrack, in action.

State of the art in 3D modeling of bone structures from images.

The use of non-invasive procedures in medical imaging applied to the analysis of the morphology and functionality of an organ in its full dimensions, remains a huge challenge for the fundamental and applied research. In particular, the constantly evolving image sources in the biomedical fields allow for different observations of the bone structure. The multimodal fusion of the obtained images allows us to analyse those structures within their full dimensioniality (3D).

The 3d modeling of bone structures from images can be achieved with invasive, minimally-invasive, or non-invasives techniques. Farida Chériet will present the state-of-the-art of each one of these categories, relying mostly on the modeling of a human body's bone structure in the context of the development of medical diagnostic and treatment simulation tools.

Computer Assisted Surgery

The Navitrack System is an innovative computer-asisted surgery (CAS) system that provides patient-specific 3-D images in real time to assist the surgeon in preoperative planning and surgery. Using CT scans or MRI data to create a 3-D image, Navitrack delivers a highly precise virtual model of the patient's individual anatomical structures, enabling the surgeon to track instruments and implants during surgery. The benefits are significant, including optimal implant placement and improved patient outcomes. Using an on-stage Navitrack system, Stefan Seefeld and Daniel Odermatt will present the various stages of computer-assisted surgery, from data acquisition and segmentation, to preoperative planning and real-time navigation.
