Comprehensive Electron Density Phantom

For calibration of Hounsfield Unit (HU) vs. electron density of CT radiotherapy treatment plans in research studies and experimental setups

Calibration of radiation oncology treatment plans in research studies and experimental setups
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 phantom is a tool for the calibration of Hounsfield Unit (HU) vs. electron density of radiotherapy treatment plans to optimize the dose delivered to the patient (CT/CBCT).

The Comprehensive EDP phantom is ideally suited for the creation of a HU vs the electron density table for treatment planning CT (4DCT). It consists of a water-equivalent body section and a removable/stand-alone head section with in total 16 holes for exchangeable inserts that mimic real human tissue regarding its physical and electron density according to the ICRU Report 44 and 46. Remarkably, the phantom also provides realistic tissue in the higher density range (bone).

The phantom comes with a protocol displaying physical density, electron density, electron density relative to water and effective atomic number (other values are optional).

The phantom is suitable for the high energy ranges (MeV electron, photon, and proton therapy systems).
