Digital blood flow analysis from microscopic images of mesenteric microvessel with multiple branching.

摘要: Blood flow through frog mesenteric microvessel with multiple branching, at Reynolds number 0.022, is analyzed. After pre-processing the images velocity and erythrocyte distribution profiles by image velocimetry axial tomography are obtained, respectively. The vascular parameters shape descriptors obtained processing techniques. shows variation around branching areas associated an increase in radial velocity, which up to 10% of velocity. From various locations tomograms reconstructed. Based on these contours equal concentration point-to-point cell throughout observed regions where cellular varies from 3 5%, zero identified. change shape, determined descriptors, while passing capillary significant. This passage cells, depending their orientation, also displaces walls 1.5 2.5 microm.
