Abstract
The Cardiac Assessment and Classification of Ultrasound (CACTUS) dataset is an open-graded dataset designed for the evaluation and classification of cardiac ultrasound images. The dataset was created as part of the ARQUS project, which aims to develop an autonomous robotic system capable of performing ultrasound scans and extracting quantitative measurements. This project is funded by the NSERC (Natural Sciences and Engineering Research Council of Canada). The dataset contains ultrasound images obtained from scans of the CAE Blue Phantom, a synthetic model used to simulate the human heart. These images represent a variety of heart views and exhibit different quality levels. A detailed grading schema was developed by two medical imaging experts to assess the quality of each image, which ensures that the dataset contains a diverse range of both high- and low-quality ultrasound scans. The CACTUS dataset is particularly valuable for applications in artificial intelligence, specifically in the domain of echocardiography. It has been used in the development of automated system for the classification of cardiac ultrasound images and the assessment of image quality, which can assist medical practitioners in automating these traditionally labor-intensive tasks.

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
