Comprehensive evaluation of ex vivo and in vivo tissues with ultraviolet photoacoustic remote sensing virtual histology and spectral-domain optical coherence tomography
Bibliographic record
Abstract
Rapid, accurate intraoperative assessment of excised specimens and in vivo resection sites is a critical need in tissue-conserving cancer surgeries. We develop a multimodal imaging system integrating ultraviolet photoacoustic remote sensing (UV-PARS) microscopy with spectral-domain optical coherence tomography (SD-OCT) to provide comprehensive, co-registered information for identifying atypical tissue features. 1050-nm SD-OCT generates a widefield, depth-resolved view of subsurface tissue morphology, with 9-μm axial resolution. UV-PARS produces virtual histological C-scan images of cell nuclei, at 390-nm lateral resolution. Dual-contrast in vivo mouse imaging, and ex vivo imaging of breast and prostate specimens is demonstrated, and correlated with conventional H and E staining.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
