Advances in Imaging for Atrial Fibrillation Ablation

Figure 5

Real-time respiratory-gated motion compensation. A system is being developed whereby the 3D shell of the left atrium (either from CT/MR or rotational angiography) moves during the abaltion in response to respiratory motion. This example demonstrates how the trachea is automatically tracked. Image courtesy of Kawal Rhode, Kings College London and St. Thomas’ Hospital.
