- The standard phantom for the quality control checks of peripheral bone mineral densitometry in qCT
- Test reproducibility and accuracy in clinical installations and at manufacturers’ sites
- Multiple trabecular bone inserts embedded in water-equivalent plastic
The European Forearm Phantom consists of water- and bone-equivalent solid materials to test peripheral bone densitometry systems. It allows a comparison of trabecular bone examinations at different locations and on different machines as well as a comparison of axial and peripheral bone measurements.
A circular cross-section with flattened sides was chosen to model the forearm. The inserts simulate trabecular bone with different CaHA densities and provide the basis for linearity checks of qCT systems. The bone-like structure is completed with a thin cortical wall surrounding the trabecular bone.
The phantom verifies reproducibility and accuracy checks of the following quantities:
- Spongiouse/trabecular and cortical volume bone mineral density (vBMD) in g/cm³
- Thickness of cortical bone in mm
- Measures of bone equivalent inserts
- Bone Mineral Contend (BMC)
