Construction of Complex Three-Dimensional Structures of the Aorta of a Particular Patient Using Finite Analytical Formulas

We have developed a method for constructing the geometry of morphologically realistic human aorta, including aortic root (Valsalva sinus), thoracic arch with branches, abdominal aorta bifurcation vessels. The creation three-dimensional model is necessary when planning surgical interventions, performing numerical modeling blood flow in aorta. anatomical structure differs different patients, especially presence various pathologies (aneurysms, stenoses, dissection). Creation an individual based on MRI, CT images requires time-consuming manual work highly computer skilled specialist. Presented simple building 3D Initially, (or selected section aorta) one patient created. For this purpose, analytical constructed from raw To build such it to divide into characteristic sections and specify defining parameters each section. another patient's base taken adjusted features structure. At that, areas pathology (stenoses aneurysms) are added if necessary. Correction basic much less time effort than creating particular scratch. One key technique ease use, eliminating monotonous labor resulting fully ready printing printer. Sections docked second order smoothness (continuous derivative between aorta).
