Abstract

The navigation of instruments, implants and patients in space has gained a broad acceptance for several years now. Especially in case of demand for minimal invasivity, navigated surgery has an enormous importance because of the decisive perceptual field expanding of the surgeons. The currently used systems in surgery are almost based on camera technology and image processing algorithms. The tracking solutions provide highly accurate three-dimensional position information of defined objects in space. On this basis, operation procedure can stepwise be assisted by a computer. Several clinical studies, by analyzing complaint rates of implanted joints and associated radiological images, could show that using navigation systems significantly decreases the implant failure.
Facing all improvements there are several disadvantages, which often are the reason for yet not navigated operating. High investment and maintenance costs, complexity in setup and operation and disturbances in the line of sight between camera and markers or leaving the permitted measurement field cause signal outages, loss of time, distraction and distrust of the technology.
The following study shows a technical analysis of current surgical navigation systems, discussing the existing problems and providing an improved procedure. Based on the state of the art and under consideration of given orthopedic guidelines, all requirements of a developing system are defined. Technically the work is based on the fusion of image processing routines with inertial sensors.
