Abstract
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 intra-operatively thanks to the development of Augmented Reality (AR), which consists in superimposing the preoperative 3-D modeling of the patient onto the real intra-operative 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.
