Magnetic Resonance Imaging (MRI)
Magnetic Resonance Imaging (MRI)
Our experimental method is cardiac MR imaging with tags. MR images are contoured and used as the basis for finite element models.
In addition, 3D strain is calculated from the tag lines. 3D myocardial strain before and after surgical remodeling has inherent value [Zhang, et al, J Thorac Cardiovasc Surg, 134: 1017, 2007] but we also use the calculated strain as the 'gold standard' when optimizing material properties.
