BD-05: 3D catheter localization for ablation in the heart by means of biplanar fluoroscopy

Developing a system for integrated planning, navigation and control of electrophysiological (EP) check-ups and ablation therapies

Atrial fibrillation is the most common form of cardiac arrhythmia, with around one million sufferers in Germany alone. This specific form of cardiac arrhythmia is associated with an increased risk of strokes, the development of cardiac insufficiency as well as general cardiovascular morbidity.

X-ray-guided catheter ablation represents an effective approach to treating atrial fibrillation. With this process, a three-dimensional superimposed image can be calculated from a pre-operative dataset (e.g. CT, MR, CACT), which is then fused with the intra-procedural x-ray images in the form of a superimposed image.

The technical goal of the project is to develop a system for the integrated planning, navigation and monitoring of electro-physiological (EP) examinations and ablation treatments. The research project is divided into several sub-aspects. The major points are catheter localization on the x-ray image as well as the development of semi or fully automatic 2D/3D registration processes for superimposing 3D volume datasets on biplanar 2D fluoroscopy images. Another important aspect is the creation of informative visualizations for navigation and monitoring during the procedure. The integration of external signals, such as sensor data measured at the tip of the catheter, with corresponding visualization is a further important element of the research project.
