A4C Valve Visibility

Start Labelling →


Project Overview

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 mitral or tricuspid valves 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 images with significant differences in valve visibility are ranked accurately.
