| Sumario: | Cerebral vascular diseases are complex to analyze directly from the input data captions offered by Computer Tomographies and Magnetic Resonances because the cerebral blood vessels are small and narrow. In this report, the reconstruction and the modelling of cerebral vascular structures are addressed. First, the medical issues on diagnosis are studied and the requirements of the problem are defined. A symbolic model of the cerebral blood vessels, which provides information of the semantics, the topology, the geometry and the volume of the vascular map is proposed and evaluated. In addition, from an input discrete representation, a seed algorithm of construction of these model which analyzes the characteristiques of the blood vessel MAT (Medial Axis Transform), its regular features as well as its anomalies is analyzed and evaluated. |
