Echo View Classification

Start Labelling →

Project Overview

We are training an AI model for detailed classification of echocardiographic views, covering 47 distinct categories.
Due to the large number of views, some challenging cases may arise.
For instance, certain views — such as the apical 3-chamber and apical 4-chamber — can appear similar, making it difficult to determine the correct label.

Please examine each image carefully to distinguish between these views.
If an image does not fit any available category, select “None of the above”.
If it fits a category but you’re unsure which one, select “Not sure”.
