Figures & data
Figure 1. Phantom skull with skull reference array on the temporal bone in the iCT. To avoid metallic artifacts, the reference star must be outside the scanning area.
Figure 2. Measurement of phantom-based target positioning error.
Figure 3. The sterile-draped patient with the skull reference array fixed in place undergoing the intraoperative CT scan.
Figure 4. Target positioning error for five measurements on the phantom skull.
Figure 5. Measurement of the target positioning error by identification of the facial nerve with a tracked needle.
Figure 6. Navigation-controlled cochleostomy. The curved needle points to the tympanic scale where the electrode is inserted.
