AI总结:
本文提出耦合3D-1D模型用于研究灌注,采用块对角预条件器并验证其鲁棒性,对比了与宏观尺度模型的差异。
摘要:
我们通过耦合组织内扩散和血管一维段扩散的多尺度模型研究灌注。我们为模型方程提出块对角预条件器,并通过数值实验验证其鲁棒性。我们通过[P. Tofts, Modelling in DCE MRI, 2012]对比了该模型与宏观尺度模型。
英文摘要:
We study perfusion by a multiscale model coupling diffusion in the tissue and diffusion along the one-dimensional segments representing the vasculature. We propose a block-diagonal preconditioner for the model equations and demonstrate its robustness by numerical experiments. We compare our model to a macroscale model by [P. Tofts, Modelling in DCE MRI, 2012].
