Purpose The anatomic relationship around the horizontal segment of petrous internal carotid artery (ICA) is complicated. Relative researches on human patients using radiographic technique are scarce. It is essential to get adequate anatomic knowledge about this region for performing some bypass procedures. Methods Using the independent software Mimics, we prospectively studied the 0.45-mm-thick...
It is very important to predict displacements and deformations of the vessels near tumor before actinotheraphy or surgery. To simulate the influence to blood vessel induced by tumor growth, cellular automata is employed to simulate the tumor growth, and the tumor geometrical model is meshed to construct the finite element model with tetrahedron cells. At the same time, the vascular geometric model...
To simulate the benign tumor growth in complex vascular environment accurately, the shape of blood vessels should be coordinated with the truth and, therefore, the mesh of geometric model constructed from the pictures of cut corpse should be rectified and refined. A strategy of rectifying vascular mesh is presented in this paper. In the method, some vertices will move along diameter direction of vessel...
