- Primary Outcome Measures
Name Time Method When determining the orientation of THS electrodes, the rotational X-ray image gives the same result as the CT-based evaluation algorithm when determining the rotation in degrees in relation to the zero axis.
- Secondary Outcome Measures
Name Time Method The postoperative position determination of the electrode tip in the XYZ coordinate system by means of CT and rotary X-ray is equivalent, that is, the same result is obtained with both methods, deviations (defined as the Euclidean distance between the two measured points) in the submillimeter range are acceptable.<br><br>The rotary X-ray is preferable to computed tomography for reasons of radiation hygiene.
