SKYSCAN "CT-analyser" or "CTan" analyses micro-CT datasets in 2D and 3D for morphometry and densitometry. It is an intuitive and comprehensive environment for processing and analysis of datasets, accurately generating the quantitative data that is the final objective of micro-CT scanning and analysis.
The software features include:
- Import and output of dataset in tiff, bmp, jpg
- Angular resampling of datasets to any solid angle
- Advanced region and volume of interest (ROI, VOI) selection tools
- Measures 3D distances and angles
- Creates maximum intensity projection (MIP) images
- Calibrates and measures density as HU, BMD or attenuation coefficient
- Image processing functions such as smooth, despeckle, morphological operations etc.
- Switch between general scientific and bone morphometry (ASBMR) parameter names
- Programmable stacking of functions (“scripting”) for customised and automated analysis
- Analysis of integrated structures within VOI in 2D, 3D
- Analysis of all individual objects within ROI/VOI in 2D, 3D
- Parameters measured (including 2D and 3D):
- Object (pore, particle, etc.) or “bone” volume
- Object or “bone” surface
- Structure or “trabecular” thickness
- Structure or “trabecular” separation, number
- Structure Model Index (SMI)
- Fragmentation index or “trabecular pattern factor”
- Euler number
- Degree of anisotropy by MIL, eigenvalues, eigenvectors and stereology
- Fractal dimension (Kolmogorov)
- Moments of inertia (x, y, polar, product), Eccentricity
- Cortical periosteal perimeter (outer perimeter of tube)
- Cortical endosteal perimeter (inner perimeter of tube)
- Detailed analysis of porosity
- Short list of measured parameters (PDF)
- Detailed description of measured parameters (PDF)
- Automated batch analysis
- Measurements validated by real and virtual phantoms
- Creates 3D models by several rendering algorithms, in formats including STL
