WebApr 12, 2024 · It includes (i) a mathematical extension and validation of the law of Laplace from a circular to a cloverleaf cross-sectional shape, and (ii) careful assessment of patient imaging studies to determine which method of aortic root measurement best represents wall stress by the extended Laplace formula. WebCircular fringe Fourier transform profilometry (CFFTP) based on a triangulation system has the capability of whole out-of-plane measurement using fewer fringes. To the best of our knowledge, the existing CFFTP [ 25, 26] calculates the displacement amount carrying the height information of the object by solving a quadratic equation.
