Statistical analysis of the human cardiac fiber architecture from DT-MRI

摘要: A statistical atlas of the cardiac fiber architecture is built for first time with a human dataset 10 healthy ex vivo hearts acquired using DT-MRI. The constructed an efficient semiautomated method where limited interactions are only required to segment myocardium. All registered automatically by and robust non linear registration method. gives better understanding architecture. study on global variability reveals that orientation more stable than laminar sheet orientation. also consistent across left ventricular AHA segments. Moreover this could be used electromechanical modeling as well basis precise extrapolation models, essential in DT-MRI acquisition.
