surgery: the next step |
|
AR in the operating room |
Medical imaging and organs modeling, based on massive introduction of computer science in medical domain, are used for diagnostic (arteries stenoses quantization, breast cancer tumour detection), monitoring the evolution of diseases (by registration of same patient's datas). |

Augmented Reality is a solution to fuse preoperative results with the intrap context. The aim is to mix the surgeon's vision (extern, endoscopic...) with miscellaneous informations: patient images from other modalities, prereconstructed models of organs, preop planing results. The surgeon would be able to SEE THROUGH (transparent skin), SEE DIFFERENTLY (with Xrays eyes ;-) and SEE MORE (overlayed indications). Augmented reality seems be very attractive, but raises some difficulties which must be solved by research: * vision: calibration of the surgeon's vision system, features extraction, intraop model construction, * registration: preop and in situ data (different modalities, deformations...), * ergonomics: overlay images, interaction with the surgeon, * real-time and security issues. |

A large part of those developpements are limited to the preop stage. The next step is to intoduce medical imaging and modeling in the operating theatre. Results of preop planification, models of target organ's and their positioning in the real operating context would be very helpful in guiding the surgeon's gesture. |

Simultaneously, robotics technics are being used in the operating room. In the roboticaly assisted mini-invasive operations, postop trauma are greatly reduced. Articulated instruments enhance surgeon's dexterity and insure his gesture. Planification and simulation technics based on patient dependant models help the surgeon getting used to this new context before the actual operation. |
