Comprehensive Electron Density Phantom
For the calibration of Hounsfield Unit (HU) vs. electron density of CT radiotherapy treatment plans
OVERVIEW
- Suitable for the creation of the electron density calibration curve of computed tomography (CT) scanners for treatment planning systems (TPS)
- Suitable for electron, photon, and proton therapy systems
- 16 ICRU-conformal tissue-equivalent rods
The phantom excellently 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/standalone head section with 16 holes for exchangeable inserts that mimic real human tissue regarding its physical and electron density according to the ICRU Report 44 and 46.
The phantom is not only suitable for the high energy ranges (electron, photon, and proton therapy systems), but is also a valuable tool for kV energies in diagnostic imaging (e.g. Multi-Energy CT).
Remarkably, the phantom provides realistic tissue simulation and values also in the high-density range (bone).
