Abstract

fetched live from OpenAlex

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.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
