This model is part of an online e-learning module on echocardiography for medical students of the University of Groningen, bridging the gap between 3D anatomical structures and their 2D representatives in echo planes. The other half of the model of the subcostal 4 chamber echo plane has been cut out of an anatomical model of the heart. Its original, a model called ‘Echocardiography: subcostal 4 chamber echo plane’ can be found following this link: https://skfb.ly/6oQBC
