We are training an AI to automatically detect and assess the clarity of valve visibility in echocardiogram images, specifically in the Parasternal Long Axis View (PLAX). To achieve this, we are ranking images based on how clearly each valve (mitral or aortic) is visible, from the most clearly visible to the least clearly 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. We are addressing the mitral and aortic valves separately.
