DFG-Forschergruppe FOR 1585
The DFG research project “Multi-Port bone surgery using the example of the temporal bone” (MUKNO) is a cooperation between the ORL-clinic in Düsseldorf, the “WZL” of the RWTH Aachen and the “Interactive Graphics System Group” of the TU Darmstadt. The aim of the project is to investigate how minimally traumatic surgical procedures at the otobasis can be accomplished. The main challenge here is not to damage any important structures such as the facial nerve or the carotid artery. So far, the surgeon dissects all collision structures in the surgical field which means a high risk for the patient. In future, only three drilling canals should be used. Through these canals the instruments are inserted and the computer supports the surgeon during the navigation. In order to keep the complication rate under 0.5 %, the process chain has to be controllable. This means in every step of the chain – from the image acquisition over the segmentation, registration and planning to the drilling – the possible error should be kept under a feasible threshold.
Particular projects of MUKNO
- Image acquisition
- Segmentation
- Registration
- Planning
Registration
The position of the instrument relative to the patient´s anatomy should be controlled during the operation. For this purpose appropriate verification images are to be acquired. After registration of the intra- and proxy-operative image data the actual instrument position can be determinated and in case of error corrected. The main challenge here is to develop a “real time” capable registration method.
