A4C Endocardial Segments

Start Labelling →


Project Overview

We are training an AI to automatically detect and assess the clarity of endocardial segment visibility in echocardiographic images, specifically in the apical four-chamber (A4C) view.
To achieve this, we are ranking images based on how clearly the endocardial segments are visible, from the clearest to the least visible.

In many cases, the difference in segment 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 segment visibility are ranked accurately.
