Hemodynamics plays an important role in the development, progress and rupture of aneurysms, and therefore, is essential for advanced diagnosis. However, existing methodologies have yet to provide detailed and accurate information of blood flow field due to their individual limitations. As a solution to the problem, we have proposed Ultrasonic-Measurement-Integrated (UMI) simulation. In this method, feedback signals derived from the difference between measured Doppler velocity and the calculated one by numerical simulation are fed back to the numerical simulation. In this paper, we validate the efficacy of three-dimensional UMI simulation by the numerical analysis with various irradiation methods of ultrasonic beam. As the result, UMI simulation improves computational accuracy and enables us to obtain more accurate information of blood flow field including wall shear stress.
