Abstract
Technological development of devices used in image-guided surgery and therapy has progressed due to the potential advantages such technology can bring to procedure efficacy and safety. This paper describes the technical design of a real-time catheter-motion sensor for use in investigating applied motion in catheter-based interventions and for use as an input device for a remote catheter navigation system. The device is comprised of three stages: the first two are passive stages used to measure axial and radial motion of the catheter and the third stage is an active brake used to impede motion. As a catheter is moved through the device, axial and radial measurement is achieved by mechanically coupling two optical encoders to the catheter. An electronic 24-bit counter and micro-controller are used to record incremental motion of the catheter. A computer loaded with a custom Python driver initializes and controls the micro-controller through a RS-232 port. The use of real clinical catheters with this device will allow the device to be used as an input to an image-guided remote catheter navigation system. User feedback may be achieved by linking a sensor in the slave device of a remote catheter navigation system, with the feedback system of the device.

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
