thelight blue at the back of the valve is bigger than the othersize of valve aperture. The velocity flow on that particularregion is slower that the other part of the vein. Thus, it ispossibly support the blood clot formation at the back ofthe valve which could lead to deep vein thrombosiscondition.c) 7 mmHighLowFigure-9. Comparison of velocity distribution for different size of valve aperture.CONCLUSIONSIn conclusion, the purpose of this study is todiagnose the early stage of DVT. From the simulationresult, it can be seen that, the value of velocity will exciteas they go through the valve. That is shows how the bloodactually flows in our body. To get more accure result,more simulation was needed to create a velocity chart topredict when the thrombus will exist at the valve based onthe velocity of blood. As the in vivo experiment wasdifficult to investigate. Therefore, the early diagnosisactually will assist physician in order to prevent thedevelopment of pulmonary embolism (PE).ACKNOWLEDGEMENTSThe authors would like to thank ResearchAcculturation Grant Scheme (RAGS R031) for thefunding of this project.
