An abdominal aortic aneurysm is defined as a local and abnormal dilation of the aortic wall that can lead to rupture and death without treatment. A useful tool for the patient's postoperative follow-up is segmentation registration to see the evolution of the aneurysm between two examinations. Here, we propose a method to automatically register the entire arterial system: the segmentation is divided in three parts (suprarenal, infrarenal zone, and iliac arteries) and each part is registered separately. We chose a rigid point set to point set registration through the iterative closest point algorithm. We also compute the displacement fields and derive a criterion to accept or reject the registration of the infrarenal zone and iliac arteries. Registration is successful in 96% of cases for the infrarenal zone, in 94% for the suprarenal zone and in 65% for the iliac arteries.Read less <
