Abstract
Despite the increased interest in robotic systems designed for bronchoscopy, the influence of the bronchial tree dynamics remains relatively unexplored. To enable robotic solutions to perform successful autonomous navigations whilst minimizing contact with the internal anatomy, they must be capable of adapting to ongoing geometric changes caused by the respiratory cycle. In this letter, we introduce a method for parameterizing these cyclic changes and present a flexible magnetic robotic catheter design that adapts its shape dynamically. Three bronchial branches (up to 4th generation bronchioles) with diverse shapes were investigated to examine the feasibility and efficacy of this approach. Reference anatomical geometry was taken from an open-source dynamic computed tomography patient dataset, and was evaluated over the breathing cycle to develop patient- and branch-specific magnetic catheter profiles and associated time-varying external magnetic fields. The system was demonstrated using dynamic Helmholtz coil actuation and showed a mean error in replicating the centerline of each of the three branches over the entire navigation of 2.1 mm, 1.4 mm, and 1.9 mm respectively.

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
