  • S0220203 Development of phantom experiment method with flexible stenosis tube for fluid simulation

説明

In this paper, we described a novel phantom experiment method with flexible stenosis tube, for use of circulatory simulation by fluid-structure coupled analysis. Recently, factional flow reserve (FFR) for evaluation approach of coronary stenosis has received a lot of attention. However previous technics is still difficult to measure the FFR values, because catheter surgery is required. To solve this problem, we have developed a novel approach based on four-dimensional computed tomography (4D-CT) image tracking and structural and fluid analysis named 4D-CT FFR, promising minimally invasive for patients. Here we demonstrated phantom experiment with flexible stenosis tube, and indicated relationship between deformations of the tube, pressure loss and flow rate, for validation of 4D-CT-FFR.
