Supplementary Material for DBS Lead Reconstruction Robustness Study

Supplementary material for a study assessing the robustness of computational lead reconstruction for deep brain stimulation across 34 patients with Parkinson's Disease or Essential Tremor. The study compares lead tip coordinates and volumes of tissue activation from two distinct postoperative CT-scans per patient. The material was authored by figshare admin karger and last updated in May 2026.

Use Cases

• Assessing the robustness of lead reconstruction routines based on comparisons of lead tip coordinates between CT scans.
• Evaluating group-level probabilistic maps of clinical improvement for Parkinson's Disease patients.
• Investigating the impact of pneumocephalus on computational normalization and lead reconstruction.
• Comparing individual-level volumes of tissue activation using Dice coefficients across different stimulation amplitudes.

Strengths

• Includes data from 34 DBS patients with two distinct postoperative CT-scans each.
• Reports specific quantitative results, including a mean lead tip translation of 0.79mm and mean Dice coefficients for VTA comparison.
• Material is associated with a peer-reviewed study methodology described in the summary.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal or cohort bias inherent to the specific patient group studied.
