Chest computed tomography (CT) scanning or magnetic resonance imaging (MRI) can be used to recreate 3-dimensional anatomy in the left atrium, thus aiding in mapping and creating contiguous lines in the left atrium.

The image on the right is a reconstructed 3-dimensional image of the right atrium in a patient undergoing atrial fibrillation ablation. The figure on the left was created with a mapping catheter using Endocardial Solutions mapping technology. It represents the endocardial shell of the right atrium and is used as the template during left atrial ablation procedures.
