Cone-Beam Electron Density Phantom

Enables Automated CT-to-density Tables for TPS Commissioning of Cone Beams

  • Patent-pending rod markers with unique identifiers are automatically located in a CT scan 
  • Automated software can process the IVDT and generate the density table 
  • Wide range of electron density values with rods designed to ICRU-44 and ICRP specifications 
  • Help ensure accurate calculations of dose distributions

Processing an image value-to-density table (IVDT) takes valuable clinic time and can be prone to operator errors. With the new Cone-Beam Electron Density Phantom, you can expedite your workflow while avoiding misplaced rods, rotated phantoms and/or incorrect selection of ROIs. Patent pending rod markers enable fast, easy, error-free IVDT generation.

Commercial release coming soon.
