Key parameters for microCT scanning
| Parameter | Description | Units |
|---|---|---|
| Voxel size | Measure of nominal spatial resolution; smaller the value the better the resolution | μm |
| X-ray tube potential (peak voltage) | Measure of X-ray energy; higher voltage results in less attenuation through denser/thicker specimens | kVp |
| X-ray intensity (current) | Electrical current through X-ray tube; higher current produces more photons and better signal-to-noise | μA |
| Integration time | Duration of time for photons to hit detector for each projection; longer times give better signal-to-noise but increases scan time | ms |
| Frame averaging (average data) | Number of repeated measurements at each projection; higher number gives better signal-to-noise but increases scan time | n |
