Product Description

Create CT-to-density tables with ease for TPS commissioning.

  • Cover a wide range of electron density values
  • Help ensure accurate calculations of dose distributions

The American Association of Physicists in Medicine1 (AAPM) and International Atomic Energy Agency2 (IAEA) report that Treatment Planning Systems (TPS) convert Hounsfield Units (HUs) to electron densities for accurate calculations of dose distributions. This is commonly done using electron density reference materials that enable the verification procedure.

The only Solid Water® Insert Holder

The CT Electron Density Phantom consists of a zero HU Solid Water® disk the size of an average pelvis. Sixteen insert chambers in the disk are designed to be used with interchangeable Tissue Mimicking Materials (TMM), used for characterization. Our standard Electron Density Insert Set includes 13 different materials with a wide range of electron density values.

Use the electron density inserts to create CT-to-density tables needed for TPS commissioning. The Solid Water disk also contains eight, 1mm diameter holes spaced at 50 mm intervals around the center of the phantom to test the geometric accuracy of the CT scanner. The same Solid Water disk can be used for calcium and iodine inserts to evaluate the Dual Energy characteristics of CT scanners.
