Multimodal Data Integration for Computer-Aided Ablation of Atrial Fibrillation

الملخص EN

Image-guided percutaneous interventions have successfully replaced invasive surgical methods in some cardiologic practice, where the use of 3D-reconstructed cardiac images, generated by magnetic resonance imaging (MRI) and computed tomography (CT), plays an important role.

To conduct computer-aided catheter ablation of atrial fibrillation accurately, multimodal information integration with electroanatomic mapping (EAM) data and MRI/CT images is considered in this work.

Specifically, we propose a variational formulation for surface reconstruction and incorporate the prior shape knowledge, which results in a level set method.

The proposed method enables simultaneous reconstruction and registration under nonrigid deformation.

Promising experimental results show the potential of the proposed approach.
