COMPUTERIZED MULTIPARAMETRIC ANALYSIS FROM IMAGES OF BLOOD-FLOW THROUGH FROG MESENTERIC ARTERIAL BIFURCATION

A computerised multiparametric procedure is developed to analyse the i mages of blood flow through various locations of the mesenteric arteri al bifurcation of frog. The data are recorded by a video microscopic s ystem land, after digitisation and pre-processing, are analysed by an IBM PC/AT based image processing system to obtain erythrocyte and velo city distribution profiles by axial tomographic and image velocimetry techniques, respectively.,The vessel radius; haematocrit, blood flow t hrough main and branch arteries and flow separation zones are determin ed from the data by various analytical procedures. In contrast to the earlier techniques the data are obtained from the same location of the vessel and thus the variability in flow parameters is minimised.
