1. A method for determining the risk of rupture of a blood vessel using a set of 2-D slice images obtained by scanning the blood vessel, the method comprising: generating a mesh model of the blood vessel using the set of 2-D slice images, wherein the mesh model reflects tissue type at different locations along the blood vessel; conducting finite element stress analysis on the mesh model with an identified blood pressure to calculate the level of stress at the different locations along the mesh model; and determining the risk of rupture of the blood vessel by analyzing the levels of stress calculated at different locations along the mesh model with respect to the tissue type to calculate and report probability of rupture of the blood vessel by using the Contiguous Element Defined Area (CEDA) method.
