Abstract

fetched live from OpenAlex

\nL'interaction d'une impulsion laser femtoseconde avec une cible solide peut induire une émission intense\nde rayonnement X dans la gamme de quelques dizaines de keV. Ce type de source présente potentiellement plusieurs\navantages sur les installations X conventionnelles en termes de performances (taille de la source, ganinie de longueur\nd'onde accessible) et de coût. Ce papier réunit les différents résultats obtenus dans le cadre du projet d'imagerie\nmédicale de I'INRS à Varennes, Québec, Canada. Ces travaux concernent d'une part l'étude quantitative de la source\nde rayons X-durs: intensité, spectre et taille de la source. D'autre part. des expériences de faisabilité ont montré la\npertinence de leur application à l'imagerie médicale. notamment dans le domaine de l'imagerie à grande résolution\nspatiale (mammographie) et dans celui de l'imagerie par soustraction d'images A deux longueurs d'onde (angiographie\ncardiaque). La principale limitation de ces expériences était la puissance moyenne de la source bridée par la faible\ncadence de l'installation laser. Les lois d'échelle déduites des expériences présentées laissent présager la poursuite de\nces travaux dans des conditions cliniques réalistes avec le développement actuel de chaîne laser de hautes cadences\n(100 Hz–1 kHz).\n

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.
