The European Spine Phantom QRM-ESP-04 is now the standard for quality control - accuracy and reproducibility - in spinal BMD quantification for more than a decade [3]. Its design is closely anthropomorphic by its outer measures and internal lumbar vertebrae inserts such that standard patient protocols can be utilized, both in DXA and QCT.
The phantoms main body consists of water-equivalent resin, the three inserts contain varying amounts of calcium hydroxyapatite (HA) to cover the full physiological range of spongeous and cortical bone densities for all age groups.

QRM-ESP-04 allows to check reproducibility and accuracy with the following quantities:

  • bone mineral content (BMC) in g for DXA
  • bone mineral area density (BMD) in g/cm2 for DXA
  • projected area (A) in cm2 for DXA
  • trabecular and cortical bone mineral density in g/cm3 for QCT
  • cortical thickness in mm for QCT
  • positioning accuracy in QCT
