Abstract:
•Overall electrode accuracy was 0.22+/-0.4 mm with only 3 (4%) electrodes out with 2 mm from the intended target.•Accuracy was significantly worse in the GPi versus the STN and on the second side implanted.•Inaccuracy occurred in the X (lateral) plane but was not related to pneumocephalus or brain shift.
