摘要：Cine MRI (amplitude image and phase contrast image) has been used to represent the blood flow velocity on the aortic aneurysm. Acquisition of images taken perpendicular to the abdominal aorta is done in free breathing and breath hold at the specified location as needed. Active Contour method or Snake (Deformable Model) has been used to perform automatic contour on amplitude image to detect the surface of the aorta and obtain the required parameter values. Furthermore, image reconstruction is performed on the object's surface from several slices of image segmentation that results with Scalar Volume Data technique (isosurface) in order to obtain the value of blood flow volume. The method has been developed and can represent animation of aortic aneurysm with blood flow velocity on each category of thrombus.
