Objective: to optimize the process of blood vessel biomechanical modeling via developing models of cerebral arterial circle. Materials and methods. Biomechanical modeling requires development of a patient-oriented three-dimensional (3D) solid-state geometric model of the object under study. This task can be resolved by computed tomography (CT) or magnetic resonance imaging (MRI). We developed the program that implements the construction of blood vessel contours from separate slices of MRI in a semi-automatic mode. These contours are exported as saved curves in a specific format to SolidWorks, where they are used to create 3D models of blood vessels. The models obtained this way take into account individual characteristics of the vascular system structure 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 2D slices of tomograms are presented. Conclusion. The developed software allows semi-automatic loading of DICOM images and obtaining flat cross-sections (MRI slices) of vessels on their basis, as well as transferring them for further processing into computer-aided design systems.
