Abstract
Many of the developments in the field of ultrasound imaging are focused on technological improvements to improve the signal to noise of the instrumentation or in the use of new techniques to increase the soft tissue contrast. Contrast in an ultrasound image is based on the strength of backscattered ultrasound. Increase in the transducer bandwidth increases the ultrasound spatial resolution, leading to higher frequencies being used to image smaller structures to provide better axial and lateral resolution. The use of acoustic microscopy has helped in reproducing scattering patterns using smaller diameter beads at frequencies between 100 and 1,000 MHz. Investigations have been conducted using instrumentation that allows ultrasonic interrogation with frequencies ranging between 1-1000 MHz.

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
