The Electron Density Phantom (EDP) is an important tool to calibrate radiation oncology treatment plans to ptimize delivered dose to the patient.
​
​The Electron Density Phantom QRM-EDP houses inserts providing 5 different tissue equivalent materials used for the HU to electron density calibration of CT scanners and radiation therapy treatment planning systems.​ All tissue equivalents represent the real human tissue regarding its physical density and electron density.
​
The new revised edition of the EDP provides tissue equivalent realistic physical densities AND electron densities of human tissues of highest interest in radiation oncology treatment planing. The non-accordance of these values is a major handicap of other available electron density (or tissue equivalent) phantoms. Particularly in the higher density range (bone), this is the first phantom that provides realistic tissue simulation and values.
