In conclusion, it could be demonstrated that the developed MBS-model is suitable for simulating ground reaction forces of dogs during walking. In forthcoming investigations the model will be developed...
Analysis of Cardiac Torsion by Strain Calculation with MR Phase-contrast Image
Heart Twist MR-PC Three-dimensional Analysis Medical Image
2009/6/1
Torsion movement of the left ventricle has significance in ventricle contraction and dilation. In this study, we propose methods of analyzing torsion movement of whole body and local region of left ve...
Calculation of arterial wall temperature in atherosclerotic arteries: effect of pulsatile flow, arterial geometry, and plaque structure
arterial wall temperature atherosclerotic arteries pulsatile flow arterial geometry plaque structure
2010/2/26
The results indicate that direct temperature measurements should be taken (1) as close as possible to the plaque/lumen surface, as the calculations show a significant drop in temperature within 120 mi...
In-vivo coronary flow profiling based on biplane angiograms: influence of geometric simplifications on the three-dimensional reconstruction and wall shear stress calculation
In-vivo coronary flow profiling biplane angiograms
2010/2/26
We investigated the influence of two methods of lumen reconstruction, assuming circular versus elliptical cross-sections and using different resolutions for the cross-section reconstructions along the...
