MicroCT imaging

Definition

MicroCT imaging, or micro-computed tomography, is a high-resolution imaging technique that provides detailed 3D images of small objects at the micro-scale. This technology is essential in visualizing internal structures without destroying the sample, making it particularly useful for assessing bone architecture and understanding vascular networks in regenerative medicine.

5 Must Know Facts For Your Next Test

1. MicroCT imaging offers voxel resolutions as low as a few micrometers, enabling the visualization of intricate bone structures and vascular networks.
2. This imaging technique allows for non-destructive analysis, meaning samples can be imaged multiple times without altering their properties.
3. In bone tissue engineering, microCT imaging is crucial for evaluating scaffold porosity and connectivity, which are essential for successful bone regeneration.
4. MicroCT can also be used to monitor angiogenesis by visualizing blood vessel formation within engineered tissues over time.
5. The integration of microCT imaging with other techniques like histology and biomechanics can provide comprehensive insights into both bone and vascular development.
