Sagittal Image Segmentation from Patients with Abdominal Aortic Aneurysms

Abstract: Early detection in patients with abdominal aortic aneurysm (AAA) is essential to reduce the rupture risk of aortic wall that cause bleeding and often lead to death. The position and shape of AAA is important to complete the diagnosis of doctors in planning the clinical treatment. The segmentation of sagittal image to get aorta play important rule to them, but manual segmentation methods is timeconsuming. The characteristics of sagittal image have a gray level that is almost the same between oneorgans to another so it is difficult segmented. This research proposes an excellent semi-automaticsegmentation method to segmentation the sagittal MRI image base connected component labellingmethod. 5 sagittal image specific from a patient with small AAA is used to implemented this propose method. All images were success segmented. The aorta as a result of this proposes method is the best than the Chan-Vese segmentation method and manual segmentation method.
