A novel meshing algorithm generates high-quality 3D meshes for heterogeneous soft tissues, preserving anatomical borders during finite element method simulations for accurate deformation analysis.

Area of Science:

  • Biomedical Engineering
  • Computational Anatomy
  • Finite Element Analysis

Background:

  • Accurate soft tissue simulation requires preserving interfaces between heterogeneous anatomical structures.
  • Existing meshing methods struggle with complex geometries and maintaining tissue boundaries.

Purpose of the Study:

  • To introduce a new, automated meshing algorithm for generating high-quality 3D meshes from triangle surfaces.
  • To ensure the preservation of borders between adjacent tissues in composite material simulations.

Main Methods:

  • Development of a novel meshing algorithm designed for automatic, high-quality 3D mesh generation.
  • Algorithm processes input triangle surfaces, focusing on border preservation and handling complex geometries.

Main Results:

  • The algorithm successfully generates high-quality 3D meshes, even for complex anatomical structures.
  • It robustly preserves borders between adjacent tissues, crucial for accurate composite material deformation.
  • Processing time is dependent on mesh size, not topology, enabling predictable performance.

Conclusions:

  • The presented meshing algorithm effectively addresses the challenge of simulating heterogeneous soft tissues.
  • Its robustness, automation, and predictable processing time make it suitable for time-dependent simulations, including intraoperative adaptation.
