QRM-DEP-002 The phantom is specially designed for dual energy (DE) purposes and can be used for quality assurance, scanner performance and evaluation of different DE post-processing techniques. Research in computed tomography is currently focused on using dual energy 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.
