Abstract
Deep brain stimulation (DBS) is an effective surgical treatment for Parkinson’s disease. The procedure requires precise placement of a stimulation electrode into the therapeutic target while avoiding vital anatomies (e.g. blood vessels) to prevent surgical risks. Therefore, multi-contrast imaging data are often employed to capture full anatomical details for electrode trajectory planning. However, with multiple constraints to consider from several image contrasts, surgical planning with conventional 2D-display-based neuro-navigation software can be time-consuming and challenging. Virtual reality (VR) allows intuitive interaction with 3D data, and thus is an excellent fit to navigate complex anatomy for neurosurgical planning. We present the first VR-based DBS trajectory planning system, where we used a novel voodoo doll interaction strategy to allow precise surgical target selection and a line-of-sight approach with eye-tracking to determine optimal DBS trajectories. With preliminary user studies, the proposed system demonstrates great promises for efficient and intuitive DBS planning.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
