Development of Blood Vessels

Development of Blood Vessels

The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

To improve the geometric and topological accuracy of reconstructed vascular structures.

Main Methods:

Utilized parallel transport frames for improved reconstruction.
Developed novel bifurcation and trifurcation modeling using 3D Bézier curves.
Implemented frame blending to resolve twisting issues.
Employed curvature-based adaptive sampling and mesh quality-guided frame tilting.

Main Results:

Generated 3D vascular models with superior surface mesh quality compared to previous methods.
Ensured continuous surface transitions at vascular furcations.
Created evenly distributed, non-concave, and self-intersection-free surface meshes.

Conclusions:

The proposed methodology effectively addresses the challenge of maintaining mesh quality in 3D vascular model reconstruction.
This advancement is vital for enhancing the reliability of simulation-based surgical training and planning.
