Uittreksel

Combining ultrasound measurements with finite element models (FEMs) is a novel technique to assess mechanical material parameters of vasculature. The stiffness of the FEM is calibrated iteratively until the displacements of the FEM match those measured by US. However, the influence of surrounding tissue, e.g. the spine in the case of abdominal aortas, is not taken into account. These could have a significant effect on the displacements obtained from the FEM. In this study, 4D echography of abdominal aortas was used for 3D-US speckle tracking. Next, image-based FEMs of increasing complexity were used to quantify the influence of surrounding tissue and the spine on the displacement of the aortic wall. Results were compared with speckle tracking. Both the inclusion of surrounding tissue and the spine improved the accuracy of the displacements predicted by the FEM. Especially the displacement of the lower wall in the depthdirection improved.
