- To assess the influence of image processing techniques on scaffold characterization results.
- To demonstrate the application of ASTM International principles in scaffold analysis.
Main Methods:
- Fabrication of poly(lactic-co-glycolic acid) scaffolds using supercritical carbon dioxide.
- Imaging of three structurally distinct scaffolds using scanning electron microscopy, micro X-ray computed tomography, magnetic resonance imaging, and terahertz pulsed imaging.
- Image processing of 2D images to determine scaffold properties.
Main Results:
- Different imaging modalities and image processing techniques yield varying scaffold characterization results.
- The choice of imaging and analysis significantly influences the determination of scaffold properties.
- Demonstrated the capabilities of multiple imaging techniques for scaffold evaluation.
Conclusions:
