ab: Summary: This paper presents an effective computational technique for
    reconstructing a three-dimensional shape of an abdominal aortic
    aneurysm (AAA), from a limited number of computed tomography (CT)
    images. The three-dimensional template geometry of a healthy abdominal
    aorta is used as a priori knowledge, and the template geometry is
    deformed by extended free-form deformation (EFFD), to generate a
    patient-specific AAA geometry. A two-step optimization scheme is
    devised to find an optimal set of EFFD parameters that match the
    cross-section of a deformed template with an AAA contour shown in a CT
    image. The geometric continuity of a deformed model is maintained by
    raising the order of the polynomial function used in EFFD. Experimental
    results show that the proposed method creates the three-dimensional
    shape of AAA suitable for structural finite element analysis and
    computational fluid dynamics for medical diagnosis.
