X-ray computer Tomography (XRT / CT): Non-invasive 3D imaging of internal structures

X-ray tomography (XRT) or micro-computer tomography (μCT) is a technique to measure non-invasively and non-destructively the threedimensional (3D) structure of an object with a spatial resolution down to 1 μm and in a time scale of minutes.

The scanner is equipped with two different X-ray sources which makes it suited for a broad range of applications, like e.g. food products, plants, seeds, fibres, wood, paper, rocks, soil, etc.

Technical Details

Phoenix v[tome]x m of General Electric

  • Unique dual X-ray tube configuration for high power μCT as well as high resolution nanoCT, equipped with internal cooling for long time stability
  • 240 kV/320 W microfocus CT system suitable for high absorbing materials having a pixel size down to 3 μm
  • 180 kV / 15 W nanofocus X-ray tube with a pixel size down to 1 μm
  • Focus-object-distance from 5 mm to 600 mm
  • Maximum 3D scanning field of view up to Ø 300mm x 400 mm
  • Maximum sample weight of 50 kg
  • Granite-based precision 4-axes manipulator for long-term stability
  • 2D X-ray imaging possible
  • 3D computed tomography possible

Applications

The XRT is suitable to measure the 3D structure with high spatial resolution of a broad range of product ranging from small (<mm-sized) low dense materials to large high dense (up to 40 cm, 50 kg) materials within minutes. It is therefore suitable for an enormous broad range of applications.

Examples of application areas are:

  • Solid and semi-solid foods like foams, emulsions, meat(replacers), cheese, bread, cereals, etc.
  • Dynamical behaviour (stability in time) of above mentioned food systems
  • Colloidal particles in foods like fibres, starch granules, emulsion droplets, etc.
  • Root growth of plants in the soil
  • Soil morphology and soil macro fauna
  • Insects, fish, feathers, birds and other small animals
  • Plants, seeds, fibres, wood, paper
  • Rock morphology
  • Composite materials
  • 3D metrology
