Dual Energy CT Phantom
For the evaluation of different DE post-processing techniques, quality assurance and scanner performance
- D100 compatible
- create virtual non-contrast images
- CaHA 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 and V5 are perfect tools for testing the CT scanner performance as well as for the evaluation of different post-processing CT techniques.
Moreover, there are several options available for the Dual Energy CT Phantom, for example, the Thorax and Abdomen Phantom (see also options section).
