Fig. 2From: Micro-CT – a digital 3D microstructural voyage into scaffolds: a systematic review of the reported methods and resultsSchematic illustration showing the basics of micro-CT. Cone-beam X-rays travel from the source to the detector through the sample with attenuation, and a gray-scale projection image is acquired at each rotation angle. Projection images are then reconstructed, and the reconstructed image dataset is used for analysis. The red dashed line indicates the vertical position of the reconstructed image, i.e., the cross-sectional imageBack to article page
