Vascular texture modeling for image interpretation

In this paper, it is shown that pathological changes of vascular networks, inside an extensive organ, influence textures observed on medical images. A 3D, dynamic model of the organ and its vascular system was developed, and it enables to control the tissue perfusion. To render CT scan-like images, the acquisition process was also modeled. The proposed approach is applied to simulate the development of the hepatic vascular system and to induce hyper- and hypo-vascularized lesions inside the liver. The texture analysis of the obtained images is then performed. It shows that textural features can characterize regions changed by pathological processes as far as the acquisition conditions are precisely are presicely controlled.
