Dual Energy CT Phantom

For CT quality assurance, scanner performance checks and evaluation of post-processing techniques


  • D100 compatible
  • Provides different virtual non-contrast lesions
  • Ca++ and iodine inclusions of different size and density


Dual Energy in CT is used to distinguish between different tissues on CT images: Some lesions can be detected as equal to the surrounding material at one energy whereas a contrast is visible using different energies.

The Dual Energy Phantoms V2, V5 are perfect tools for testing the CT scanner performance as well as for the evaluation of different post processing CT techniques.

Moreover, the Dual Energy CT Phantom fits into the Thorax, Abdomen and Head Phantom.
