Different projects arise:
For the brain mapping algorithm we
combine all three essential pieces of information: The coil positions for
stimulation, the corresponding muscle responses, and the characteristic
field of the coil used. The main idea is to assume a monotonic functional
relation between the electric field strength at the representation point and
the evoked muscle response. Using a refined algorithm for Correlation Ratio
and Kendall's rank coefficient TAU, we are able to calculate likelihood maps
for the representation of specific muscles.
We use Möller-Wedel's latest OR-microscope and, together with IBG Technologies, a motorized assistance system is under development. This system makes it possible to combine pre- and intraoperative images and to simplify the useage of the microscope.
Currently, the microscope must be adjusted manually by the surgeon. To do this, he has to hand back the instruments, enable the microscope, adjust its position, take the instruments and finally he has to find his way back into the operation area. These steps increase the risk of infections and incidents. After having motorized the microscope the surgeon can easily control it using a remote control. This reduces operation time and thus the patient can be kept in anesthesia for a shorter time.
Presenting additional information
It is also possible to display preoperative data in the actual microscope view with a special mirror system. The MRT- and X-ray-images shall be presented at the correct position and the origional size. On top of this, tissue and vessel structures will be calculated from these images and will help the surgeon to navigate.
Integration of Optical coherence tomography
Optical coherence tomography (OCT) is a relatively new method, which can be used for diagnosis by the surgeon. An OCT system will be integrated in the motorized microscope and can be positioned automatically.
