From: Artificial intelligence prediction of age from echocardiography as a marker for cardiovascular disease

Fig. 3

Guided backpropagation interpretability method highlighting the most important regions of interest for the model to make determination of age for each echocardiographic view: a A4C, b PLAX, c SC, and d A2C. As highlighted by the heatmap and the white arrows, the regions of the crux cordis, mitral valve, and the mitral annulus are highlighted across views.
