Summary:

Objective: to optimize the process of biomechanical modeling of blood vessels on the example of creating models of the arterial circle of the brain. Material and Methods. Biomechanical modeling requires the creation of a patient-oriented three-dimensional solid-state geometric model of the object under study. This problem can be solved by computer data processing (CT) or magnetic resonance (MRI) tomography. A program that implements the construction of blood vessel contours on individual sections of MRI in semi-automatic mode. These contours are exported as saved curves in a specifc format to SolidWorks, where they are used to create three-dimensional models of blood vessels. The models obtained in this way take into account the personal characteristics of the structure of the vascular bed of a particular patient and can be used in the process of biomechanical modeling. Results. The results of the program implementation of the recursive frontal growth method for processing two- dimensional slices of tomograms are presented. Conclusion. The developed software allows semi- automatic loading of DICOM images and obtaining fat sections of vessels on their basis, as well as transferring them for further processing into computer-aided design systems.

Summary:

Modern methods of diagnosing of maxillary bones in various clinical situations presume a method of computer tomography. In some cases, the treatment planning according to three-dimensional image cannot be performed and the question of creation of the biomechanical model study area arises. Various methods of computer-aided design and three-dimensional modeling are worth while using to achieve the realization of the task.
