Cone-Beam Electron Density Phantom

Simplify your IVDT-Related Workflows

  • Expanded phantom size and scanning options
  • Exquisite adherence to ICRU-44 and ICRP material performance
  • Supports complete IVDT automation with patent-pending rod marker technology
  • Easy to transport, align, and use


Generating accurate IVDT calibrations for radiation therapy is easier than ever with the new Cone-Beam Electron Density Phantom from Gammex, a proven leader in Tissue-Mimicking Materials (TMM).

From self-aligning rods designed to reduce human error, to a rolling case that protects the phantom’s integrity, to high equivalency materials that thoroughly test your modern wide-beam CT scanner, this phantom meets your clinical and workflow needs.

Processing an IVDT is easier, too. Our patent-pending rod markers uniquely identify each material during the CT scan. This enables automated IVDT analysis, saving valuable time and reducing risk of error.

Rods

Patent-pending rods can be uniquely identified
during the CT scan.
