Abstract
Given the widespread use of plane-wave ultrasound imaging in biomedical diagnostics applications, it is important to have a highly efficient mechanism for image reconstruction and enhancement. This work demonstrates how one can enhance 2D ultrasound envelope data (produced by a fast Fourier-domain beamforming method) using lightweight convolutional neural networks (CNNs). These CNNs are based on a well-known and highly efficient network targeting single-image superresolution tasks. Using three experimental datasets, we show that our approach leads to better-quality ultrasound images compared to conventional delay-and-sum beamforming.

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
