Abstract
In neurovascular surgery, and in particular surgery for arteriovenous malformations (AVMs), the surgeon maps pre-operative images to the patient on the operating table to aid in vessel localization and resection. This type of spatial mapping is not trivial, is time consuming, and may be prone to error. Using augmented reality (AR) we can register the microscope/camera image of the patient to pre-operative data in order to help the surgeon better understand the topology and locations of vessels that lie below the visible surface of the cortex. In this work we describe a prototype system, developed using open source software and built with off-the-shelf hardware, for AR visualization for AVM neurosurgery. Furthermore, we consider two visualization techniques, colour-coding and chromadepth, to enhance the depth perception of vessels.

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
