Identifying Myocardial Mechanical Properties from MRI Using an Orthotropic Constitutive Modelata of cardiac anatomy, structure and function. Personalised anatomical LV models were fitted to image data from four canine hearts. Diffusion tensor MRI data from the same hearts were parameterised using finite element fitting to provide fibre angle fields that represent longitudinal axes of the my胎儿 发表于 2025-3-31 08:30:39
Evaluating Local Contractions from Large Deformations Using Affine Invariant Spectral GeometryCT). Our approach is based on metric invariants in spectral geometry coupled to a non-rigid alignment algorithm, and can be implemented on data obtained by any modality as only a segmented surface is used. We assume local affine movement of the tissue, and generate a global piecewise constant affine
