Abstract
An ultrasound probe holder is designed for use in the prostate brachytherapy procedure. The holder comprises a passive-jointed stabilizer that can be used to position, manipulate and lock in place the ultrasound probe, and a tracker mechanism to provide the position and orientation of the probe in 3D space. The information obtained from the integrated stabilizer-tracker mechanism can be utilized in image-guided robot-assisted prostate brachytherapy procedures. Performance tests show that the tracker assembly can acquire the position and orientation of the ultrasound probe with an average displacement accuracy of 0.66 mm and roll, pitch and yaw angular accuracies of 0.24deg, 0.38deg and 0.19deg, 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
