Abstract

fetched live from OpenAlex

Abstract Three‐dimensional (3D) imaging is now extensively used for studying ancient human and animal bones. This method has been consensually adopted by palaeoanthropologists, but its interest in palaeopathology has been challenged. The aim of this paper is to illustrate the contribution of 3D reconstructions to retrospective diagnosis in palaeopathology. We selected six palaeopathological cases among our research corpus representing three nosographic categories (trauma, infection and neoplasia) from various periods ranging from the Middle Palaeolithic to the beginning of the Modern Era. For each case, we compared the diagnostic value of plain X‐ray, computed tomography (CT) slices, and 3D reconstructions. The latter were performed using TIVMI program, a free software for research use developed by one of us. Reconstructions are obtained by surface extraction that follows a segmentation process. We showed that this 3D method allowed reconstructing/quantifying pathological processes on ancient bones, usefully supplementing conventional radiological analyses and clearly bringing an added value to retrospective diagnosis in palaeopathology.

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.
