Abstract
A method and a device for reference image adapting in the field of fluoroscopy-controlled interventional repair of abdominal aortic aneurisms on angiography systems are proposed. Displacements which can be brought about as a result of introducing instruments, such as when a stent is deployed in an aorta, are automatically corrected. It is also possible to correct such displacements which initially cannot be perceived in the image due to the angle of view.

A method for adapting a reference image, comprising:
- registering and overlaying a fluoroscopic image of blood vessels in a target region with the reference image;
- extracting an assumed course of the blood vessels from the reference image;
- determining a current vessel course based on a position of an instrument introduced in the target region;
- and
- correcting the current vessel course based on the assumed course of the blood vessels for adapting the reference image.
