Automated Risk Stratification of Peripheral Artery Disease via Optimized Volume Rendering and Vascular Biomarkers
Bibliographic record
Abstract
Peripheral artery disease (PAD) is a progressive vascular condition requiring precise diagnostic tools for effective risk stratification.This study presents a novel computational framework that leverages optimized volume rendering, dynamic illumination, and quantitative vascular analysis to enhance the evaluation of PAD.The proposed system integrates real-time plaque density and vascular curvature assessments, providing noninvasive, efficient, and accurate diagnostics.The framework offers automated clinical decision support, reducing interobserver variability and improving diagnostic workflows.Initial validation demonstrated its ability to classify PAD risk effectively, with plaque density averaging 0.85 and vascular curvature averaging 1.3, correctly identifying high-risk cases within the tested cohort.This framework represents a transformative approach to PAD diagnostics, supporting early intervention and personalized patient management.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
