  • Micro-tomography (microCT)
  • Micro-computed tomography (micro-CT) is a non-destructive imaging technique, which uses X-rays for the rapid digitisation of specimens in three dimensions. The ability of micro-CT to visualise the internal and external features of an object makes this technique a useful tool in a variety of biological research fields such as taxonomy and systematics, developmental research and functional morphology.

     

    IMBBC has a Skyscan 1172 micro-CT scanner (Bruker, Belgium), which can be used to scan both hard- and soft-bodied organisms, but also fossils, materials and other small-sized structures. This microtomograph is offered as a service to external users in order to create 3D objects and to perform 3D analysis.

     

    The scanner uses a tungsten X-ray source with an anode voltage ranging from 20 to 100 kV, 11 MP CCD camera (4000 × 2672 pixel) and a maximal resolution of < 0.8 μm/pixel. The maximum object size that can be scanned is 50mm in diameter. The scanning duration depends on the sample size and the selected scanning parameters (resolution, averaging frames, etc).

The invited speakers presented their work which was relevant with tomographic data providing tips and tricks to the audience about the creation, the reconstruction and the analysis of a micro-CT dataset. http://bioimaginglab.hcmr.gr/2019/11/05/bioimaging-gr-workshop-for-micro-ct-2/
