Spectral CT Phantom

For testing multi-energy or photo-counting CT protocols and post processing techniques


  • D100 compatible
  • Modular phantom for multi-energy or photon-counting setups, for QA and studies
  • Ideal for material characterization and quantification of tissue-equivalent materials
  • Provide different lesions for spectral CT
  • Ca++ and iodine rods


The Spectral CT Phantom can be used to test different types of CT modalities with dual-energy, multi-energy or photon-counting setups.

The 100 mm cylinder contains 4 holes of 20 mm diameter to house different test rods of solid tissue equivalent materials as well as fillable rods that can be used with water or contrast media.

The phantom includes a set of different solid rods of Iodine, Ca-hydroxyapatite, water and soft tissue-equivalents, such as adipose, muscle, bone, and lung. Mass density, electron density and effective atomic number are provided for each material.
