Ãvaluation d'une méthode d'imagerie par résonance magnétique pour la mesure de l'épaisseur du cartilage du genou
Bibliographic record
Abstract
L'objectif général de ce projet fut l'évaluation de la variabilité d'une méthode de mesure de l'épaisseur du cartilage du genou utilisant l'imagerie par résonance magnétique. Pour atteindre cet objectif, il a fallut faire la conception et la réalisation d'un fantôme radiologique ayant trois compartiments pouvant simuler l'os, le cartilage et les tissus mous. Nous avons démontré que la méthode appliquée présente très peu de variabilité. Quelle que soit la position du fantôme dans l'aimant, la répétition d'une mesure ou un test-retest, la variabilité maximale observée est très faible. Cependant, pour les variations d'angles du fantôme, la variabilité devient problématique.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
