| Outline of Final Research Achievements |
Experiments of thrombus formation and thrombus measurement using relaxation frequency have been carried out at shear force field of solid liquid two phase flow of red blood cell and plasma. The relaxation frequency is increased as the time elapses, and is decreased after reaching the peak point. At the peak point, the value of ACT fell below the reference value, and the amount of fibrinogen is sharply decreased. It becomes clear that the peak point of the relaxation frequency matches the start of the RBCs aggregation. Calculation results of the simulation modeling of the thrombus formation process indicated that RBCs aggregation affects the relaxation frequency similarly to the experimental results
