CTwater® is a proprietary resin which exhibits the same X-ray attenuation characteristics as liquid water in the range of 70 kV to 150 kV tube voltage. It is a very stable (solid) material and can be produced in a large amount and in many shapes with a high grade on homogeneity and uniformity.

CTwater® is as well the basis of some of our popular phantoms, as the European Spine Phantom(ESP) or the Dual Energy Phantom. It is an established and widely used material for CT calibration purposes.
