Navigation and Visualisation in Endovascular Aortic Repair (Nav EVAR)
At the moment endovascular aneurysm repair (EVAR) procedures are conducted with 2D Fluoroscopy as imaging for catheter guidance. In the Nav Evar project (Navigated Contrast-Agent and Radiation Sparing Endovascular Aortic Repair) we aim to reduce the x-ray exposure and the used contrast agent during an EVAR procedure. The idea of the project is to provide a visualization based on augmented reality and a catheter navigation to reduce the use of x-ray imaging and contrast agent.
Fraunhofer MEVIS is involved in the following parts of the project:
- 3D catheter navigation based on fiber optical shape sensing and electromagnetic tracking
- 2D/3D registration of the current fluorocopy image with preoperative CTA
- Visualization of the aortic vessel system and the CT data including a virtual angioscopy and streaming to HoloLens
- Evaluation of the developed navigation and visualization
The goals of the project are implemented in cooperation with the Institute for Robotics and Cognitive Systems, University of Lübeck, the Medical Laser Center Lübeck GmbH and the Clinics for Surgery and Radiology, University Hospital Schleswig-Holstein, Lübeck.
