“…In the context of hysteroscopic interventions, our group has presented in earlier work an approach to simulate bleeding and mixing of blood with the distention fluid inside the uterus (Zatonyi et al, 2005). However, the method did not include an explicit model of the vasculature.…”

“…We illustrate this level of modeling with two examples related to the modeling of the electro-mechanical activity of the heart and the growth of brain tumors. Additional examples related to the modeling of physiological flows can be found in [11], [12], [79].…”

Abstract-Medical Image Analysis plays a crucial role in the diagnosis, planning, control and follow-up of therapy. To be combined efficiently with medical robotics, Medical Image Analysis can be supported by the development of specific computational models of the human body operating at various levels. We describe in this article a hierarchy of these computational models, including the geometrical, physical and physiological levels, and illustrate their potential use in a number of advanced medical applications including image guided, robot-assisted and simulated medical interventions. We conclude this article with scientific perspectives.

“…To be efficient, these simulators have to reproduce sensations linked to operative gestures: realistic visual perception and realistic haptic rendering through force feedback devices. Current realistic rendering, such as the computer vision laboratory of the ETZ of Zurich techniques [13,14], are fully efficient today. Force feedback was usually very expensive, making medical simulator too expensive, but recent new products such as the Phantom Omni device from Sensable Technologies (Woburn, MA, USA) reduce this limitation, thanks to an affordable price.…”

Medical image processing led to a major improvement of patient care by guiding the surgical gesture. From these initial data, new technologies of Virtual Reality and Augmented Reality can increase the potential of such images. The 3-D modeling of patients from their computed tomography scan or magnetic resonance image thus allows an improved surgical planning. Simulation offers the opportunity to train the surgical gesture before carrying it out. These two preoperative steps can be used intraoperatively thanks to the development of Augmented Reality (AR), which consists in superimposing the preoperative 3-D modeling of the patient onto the real intraoperative view of the patient. AR provides surgeons with a view in transparency of their patient and can also guide surgeons, thanks to the virtual improvement of their real surgical tools that are tracked in real-time during the procedure. In the future, by combining Augmented Reality and robotics, these image-guided systems will provide the automation of the surgical procedure, the next revolution of surgery. We will present here all these concepts applied to digestive and gynecologic procedures.
