Fast and easy positioning and universal mount makes the Catphan phantoms ideal for routine quality assurance of any CT scanner.
Comprehensive CT performance measurements
Comprehensive CT performance measurements, internationally recognised for measuring the maximum obtainable performance of axial, spiral, multislice, conebeam and volume CT scanners.
Modular Construction
The Catphan® modular design allows test modules to be interchanged.
As your testing needs change and new modules are developed you can upgrade test modules that are compatible with your Catphan® system. Additionally, the Catphan® system is ideal for traveling physicists and engineers who conduct comprehensive evaluations of CT scanners at multiple locations as they are easily transportable and no draining is required between uses.
Durable Design
Solid-cast construction eliminates material absorption of water, freezing and leaks associated with water bath phantoms, as well as problems related to varied water sources.
