Abstract
The construction and early clinical evaluation of the first 50-100-MHz ultrasound backscatter microscope (UBM) are described. This system has a frame rate of five frames per second and examined a field of view of 4 by 4 mm with axial and lateral resolution ranging from 20 to 50 mu m. The critical components of the scanner are described, including the transducer, motion system, and scan converter. Clinical studies were performed on 40 patients with varied ocular pathology. Each patient was examined with UBM using a water-bath technique similar to that used in conventional eye ultrasound. Microscopic images of the normal structures of the anterior segment including the cornea, iris, Schlemm's canal, ciliary body, and sclera are shown. Contrasting images of corneal pathology, tumors of the iris and ciliary body, and angle closure demonstrate the exceptional measurement capabilities of this imaging method. The potential of the UBM as a practical clinical instrument is discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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
