Material to mimic real human bone with respect to its physical X-ray attenuation properties


  • Solid material that mimics human bone
  • Available in different shapes and concentrations of Calcium Hydroxyapatite (CaHA)


Calcium Hydroxyapatite (CaHA) is the basic component of human bone (> 40% CaHA). It is ideal for the following applications:

  • bone calibration
  • bone density measurements
  • bone (spine, hip, etc.) in anthropomorphic phantoms
  • Ca-plugs and stenosis in coronary arteries
  • high attenuating spheres.

The basic material, which is mixed with a specific fraction of CaHA, is available as tissue equivalent or fat.

Different densities of CaHA or specified CT HU values are available.



Concentrations of Calcium Hydroxyapatite (CaHA)
for CT: 0 - 1000 mg HA / cm³
for Micro-CT: 0 - 1200 mg HA / cm³
