In order to simulate blood flow in skeletal muscle, our group has developed a finite element description of perfused skeletal muscle. This model requires input parameters concerning the vascular system, muscle contraction and the geometry of a muscle, including its aponeuroses. The objective of the present paper is to create a geometrical reconstruction of the rat gastrocnemius medialis muscle that can be incorporated in the finite element model. Since this muscle is connected to the plantaris and the gastrocnemius lateralis muscle, a detailed computer graphical reconstruction of the triceps surae muscle, based on histological cross-sections, has been accomplished first. Using this reconstruction, relevant sections were selected to create the finite element mesh of the gastrocnemius medialis muscle. Special attention was payed to the location of the aponeuroses. The mesh can be used in finite element simulations of perfused skeletal muscle.
为了模拟骨骼肌中的血流，我们团队开发了一种灌注骨骼肌的有限元描述方法。该模型需要有关血管系统、肌肉收缩以及肌肉几何形状（包括其腱膜）的输入参数。本文的目的是创建大鼠腓肠肌内侧头肌肉的几何重建模型，以便将其纳入有限元模型。由于该肌肉与跖肌和腓肠肌外侧头相连，因此首先基于组织学横截面完成了小腿三头肌的详细计算机图形重建。利用该重建结果，选择相关截面来创建腓肠肌内侧头肌肉的有限元网格。特别关注了腱膜的位置。该网格可用于灌注骨骼肌的有限元模拟。
