Potential for Reducing Radiation Dose in Proximal Tibia Plate Fixation Using Depth Camera Augmented Fluoroscopy (DeCAF)
Bibliographic record
Abstract
Mobile C-arm x-ray machines are commonly used in orthopaedic trauma surgeries to visualize internal anatomy. However, the use of scouting images to aid C-arm positioning during these procedures can prolong operating time and increase radiation exposure. Our Depth Camera Augmented Fluoroscopy (DeCAF) device is designed to reduce the number of x-ray images needed by overlaying the fluoroscopic images onto a live video of the patient’s surface anatomy. In this study, we demonstrate in a simulated operating room (OR) environment that the DeCAF system has clinically acceptable overlay accuracy (1.3 ± 0.2 mm) and allowed the surgeon to substantially eliminate use of x-rays while fixing proximal tibial plates in acceptable positions without significantly changing the time required (p = 0.72). This justifies proceeding to live clinical evaluations.

How this classification was reachedexpand
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.
