We study the problem of segmenting reconstructing and analyzing the structure growth of thrombi clots in blood vessels in vivo based on 2-photon microscopic image data. First we develop an algorithm for segmenting clots in 3D microscopic images based on density-based clustering and methods for dealing with imaging artifacts. Next we apply the union-of-balls or alpha-shape algorithm to reconstruct the boundary of clots in 3D. Finally we perform experimental studies and analysis on the reconstructed clots and obtain quantitative data of thrombus growth and structures. We conduct experiments on laser-induced injuries in vessels of two types of mice the wild type and the type with low levels of coagulation factor VII and analyze and compare the developing clot structures based on their reconstructed clots from image data. The results we obtain are of biomedical significance. Our quantitative analysis of the clot composition leads to better .
