Designed on the basis of the well established European Spine Phantom (ESP) the QRM-DXA-Spine-QA-Phantom incorporates a simplified and more cost effective design of the vertebrae specifically developed for quality assurance (QA) and stability monitoring of Dual X-ray Absorptiometry (DXA) devices.

The complex vertebrae of the ESP are replaced by a more dedicated shape explicitly adapted to the needs of a DXA QA-Phantom.
With the QRM-DXA-Spine-QA-Phantom, areal Bone Mineral Density (aBMD) can be easily determined in AP and lateral projections.

Other HA densities of the vertebra are available upon request.

Benefits:

  • bone mineral content (BMC) in g
  • bone mineral areal density (BMD) in g/cm2 for DXA AP and lateral projections
  • projected area (A) in cm2
