Conditions
Interventions
Group 1: Image data from patients with DBS (deep brain stimulation) implantation are analyzed retrospectively with regard to the rotation and position of the DBS electrodes.

Inclusion criteria
Inclusion criteria: All patients who received a directional DBS implantation followed by postoperative CT and rotary X-ray as part of the regular follow-up.
Exclusion criteria
Exclusion criteria: Incomplete imaging.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 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
| Measure | Time frame |
|---|---|
| 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. The rotary X-ray is preferable to computed tomography for reasons of radiation hygiene. | — |
