Research in computed tomography is currently focused on using Dual Energy (DE) to distinguish between different tissues on CT images.
The DEP-002 is the first phantom providing the opportunity to test CT-scanner performance and to evaluate different DE post processing techniques.
Therefore the phantom provides different virtual non-contrast lesions.
The different cylindrical lesions consists of Ca++ or iodine. For example, in the CT-images some lesion‘s CT-values (HU) can be detected as equal to the surrounding material at one energy (e.g. 120 kV) and with a contrast at other energies (e.g. 80 / 140 kV).
The DEP-002 fits to our additionally available thorax phantom. Extension rings, to simulate obese patients are available, as well.
