From: The role of the pulmonary veins on left atrial flow patterns and thrombus formation

Angles quantifying the configuration of the pulmonary veins in the left atria and the relation with the left atrial appendage (LAA). (a) The LA skeleton, depicted in black, is computed linking the barycentres of the different LA sub-structures; (b) Top view of the left atrium \(\alpha\), \(\beta\), \(\gamma\) angles, together with the \(L_{\alpha }\) and \(L_{\beta }\) distances; (c) Lateral view of the left atrium with the computed \(\phi\) angles.
