Electron Density Phantom, D100

For the calibration of Hounsfield Unit (HU) vs. electron density of CT/CBCT radiotherapy treatment plans

  • D100 compatible
  • Calibration of radiation oncology treatment plans
  • Optimization of the delivered dose to the patient
  • Provides realistic tissue simulation and values within the higher density range (bones)
  • Further/multiple tissue-equivalent inserts are available upon request


The QRM-90110 houses 5 different exchangeable tissue-equivalent material inserts used for the HU to electron density calibration of CT/CBCT scanners and radiation therapy treatment planning systems.

All tissue-equivalent materials represent the real human tissue with respect to physical density and electron density (acc. to ICRU Report 44 and 46) which are of highest interest in radiation oncology treatment planning
