Detection of rigid transformations of abdominal stent grafts using intensity based image registration at low-field magnetic strength

Research output: Contribution to conferencePoster

Abstract

The presence of endoleaks after implantation of abdominal aortic stent grafts is a severe problem. Their origin is not yet fully known, but might be
dependent on patient position. In this research a low-field MRI scanner with the capability of changing the position of a subject is used. Two
different stents are imaged in this scanner and their translation is estimated by image registration. The ability of intensity based image registration
to accurately detect this translation was assessed. Estimation errors smaller than 1 mm were found and it can therefore be concluded that rigid
transformations of abdominal aortic stent grafts can be detected.
