Volumetric X-ray CT for Academic and Industrial Research

  • Industrial and medical computed tomography (CT) scanners.
  • Sample dimensions from 1mm to 600mm diameter x 2m long.
  • Voxel resolution down to 5 microns.
  • High-power sources for larger, denser materials.
  • Dedicated computer facility for reconstruction, visualization and data archiving.
  • Quantitative data interpretation: dimensions, density, porosity, component ratios.
  • in situ process monitoring: fluid saturation changes, mechanical changes, strain monitoring.
  • Environmental chambers or fluid injection at confining pressures up to 10,000 psi and temperatures from -20 to 150 C.
