Area of Science:

Medical Imaging
Geometric Modeling
Computational Anatomy

Background:

Effective geometric modeling of vascular structures is vital for medical diagnosis, therapy planning, and education.
Applications demand a balance between surface smoothness, accuracy, triangle quality, and surface size.

Purpose of the Study:

To develop an advanced method for generating high-fidelity 3D vascular surfaces.
To achieve a balance of geometric properties for enhanced visualization and simulation.

Main Methods:

Extraction of vascular boundary voxels to form a 3D point cloud.
Estimation of normal vectors using covariance analysis and computation of a 3D implicit indicator function via Poisson equation.
Generation of vessel surfaces using an adaptive polygonization algorithm for visualization.

Main Results:

The method produces smooth, morphologically correct, and topologically preserved two-manifold vessel surfaces.
Surfaces are scale-adaptive to local curvature, offering improved quality and accuracy.
Fewer, well-shaped triangles are generated, enhancing surface representation.

Conclusions:

The proposed method achieves a superior balance of smoothness, accuracy, triangle quality, and surface size compared to existing approaches.
Generated vessel surfaces are suitable for demanding applications like computational fluid dynamics (CFD) and virtual interventional surgery.
