Abstract
X-ray phase contrast imaging (PCI) has shown great potential for clinical investigation of soft tissues. However, most of the existing X-ray PCI modalities require either a partially coherent source such as a synchrotron or complex setups that are barely compatible with low-dose and patient tomography. This work demonstrates the possibility to efficiently achieve PCI on a low coherence system with a conventional X-ray tube and a detector compatible with a clinical routine. This was accomplished by adapting the speckle-based imaging setup and the numerical phase retrieval processing methods to the low coherence and the low resolution of the experiment.

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
