Phantom designed for the evaluation and characterization of multi-energy and spectral CT systems. Its modular construction combines a large elliptical body with a central head module, providing two clinically relevant geometries within a single platform.
A configurable set of tissue-equivalent and material-specific inserts makes it possible to assess the system response to a wide range of materials: water and adipose tissue, iodine solutions at several concentrations, iodine cores of different diameters, calcium solutions, and blood- and brain-equivalent materials. This supports material decomposition and differentiation, iodine quantification and performance assessment in multi-energy and spectral CT imaging.
Specifications
- Elliptical body: 300 × 400 mm
