Augmented fluoroscopy. Three-dimensional whole heart MR images are fused with angiographic images to augment procedural guidance. In this case, the left pulmonary artery in a child with a Fontan circuit has been stented. The optimal angulation for imaging is predetermined using the MR dataset. Blue ring markers on the MRI dataset are used to guide the positioning of the stent. The images show good registration on the angiogram after stenting has taken place.
