5.내 용 :


A computer model was produced of the hemodynamics within the carotid bifurcation with the ultimate aim of assessing the relationships between low or oscillatory shear stress and monocyte / macrohage density, and between the production of matrix metalloproteinases and wall deformation. The geometry of carotid artery including wall thickness was reconstructed from the Spin-echo MRI by the image segmentation and the reverse engineering technique of CAD. The local flow and stress analysis is performed by finite element analysis using a slightly modified version of the commercial code ADINA and ADINA-F. Boundary conditions at the common and internal carotids are applied based on the velocity vector field from blood flow information of MRI. The effects of pathological geometries are considered in relation to the anticipated correlations described above
