The proposed technique effectively reconstructs complex boundary surfaces in various 3D biomedical images.
The method overcomes limitations inherent in standard isosurface-extracting techniques for 3D image reconstruction.
Demonstrated performance and advantages through numerous examples from diverse 3D biomedical imaging modalities.

Conclusions:

The novel computational framework provides a robust solution for boundary surface detection and approximation in 3D biomedical imaging.
This approach simplifies complex surface reconstruction challenges by leveraging isosurface extraction.
The method shows significant potential for enhancing the analysis and interpretation of 3D biomedical data.
