Аннотация:The rupture of cerebral aneurysms leads to severe consequences for patients’ lives and health. Understanding blood flow hemodynamics can provide critical insights into aneurysm condition and help predict rupture risk. Such data can be obtained through computational modeling. Bench testing using optical flow visualization methods like Particle Image Velocimetry (PIV) is essential for validating computational models. We need to develop an accurate experimental model to properly reproduce simulation conditions in bench tests. This study presents a technology for creating brain vessel phantom models with aneurysms based on patient-specific data. Various phantom fabrication approaches were tested, ranging from simplified geometries to models replicating actual vessel anatomy. We present a comprehensive methodology for fabricating patient-specific cerebral aneurysm silicone phantoms derived from clinical imaging data. The phantoms were used for both computational modeling and bench testing. The experimental setup enabled simulation of both steady and pulsatile flow conditions, replicating physiological blood flow. The results demonstrated the capability to visualize complex flow patterns in cerebral vessels with aneurysms using the phantom. These findings showed strong agreement with Computational Fluid Dynamics (CFD) simulation results, confirming the model’s reliability for hemodynamic studies.
