A Framework for Evaluating Myocardial Stiffness Using 3D-Printed Hearts
[article]
2021
bioRxiv
pre-print
Preserved Fulltext
We have developed 3D-printed heart phantoms of known myocardium-mimicking stiffness and MRI relaxation properties and incorporated the heart phantoms within a highly controlled MRI-compatible setup to ...
The setup enables the acquisition of experimental data needed to evaluate myocardial stiffness using computational constitutive modeling: phantom geometry, loading pressures, boundary conditions, and filling ...
In conclusion, we have developed an experimental setup for validating MRI and FEM-based myocardial passive stiffness in 3D-printed heart phantoms. ...
