Abstract
Detailed information of the velocity and pressure field of the blood flow is essential to establish an advanced diagnosis and treatment of serious circulatory diseases. Commonly used medical measurement equipments cannot measure such information, while even state-of-the-art numerical simulation cannot reproduce real blood flow accurately. In order to overcome this problem, the authors have proposed a new technique, Ultrasonic-Measurement-Integrated (UMI) simulation, that integrates ultrasonic measurement equipment and numerical, simulation, and revealed its usefulness by numerical simulation. The present report describes the development of fundamental procedure of the interface between ultrasonic equipment and simulation, and acceleration of computational speed for real time operation. By considering the tolerance of the solution, computational speed has been accelerated by a factor of 90 achieving only ten times longer computational time than real phenomena.
