In this study, we present a method for the three-dimensional reconstruction of objects obtained from histological serial sections (exemplified by those of a pennate striated skeletal muscle) and its application to the finite element method. A hyperelastic material model is used for modeling biological soft tissue. The reconstruction process relies on the direct construction of a volumetric mesh using an octree approach which leads to a stable finite element method. Stability can be expressed in the spectral matrix condition number. To visualize stress patterns within the underlying anatomy the simulation results are projected onto images of the histological scenario.
在这项研究中，我们提出了一种从组织学连续切片（以羽状横纹骨骼肌为例）中重建三维物体的方法及其在有限元方法中的应用。使用超弹性材料模型来模拟生物软组织。重建过程依赖于使用八叉树方法直接构建体网格，从而得到稳定的有限元方法。稳定性可以用谱矩阵条件数来表示。为了可视化潜在解剖结构内的应力模式，将模拟结果投影到组织学场景的图像上。
