We are training an AI to automatically detect and assess the clarity of valve visibility in echocardiographic images, specifically in the apical four-chamber (A4C) view. To achieve this, we are ranking images based on how clearly the valves (mitral or tricuspid) are visible, from the clearest to the least visible. In many cases, the difference in visibility between two images may be minimal. When this occurs, the exact order of ranking is not critical. Just ensure that the images with significant differences in valve visibility are ranked accurately.
