CTwater slabs

• Quality assurance measurements 
• For high energy photon, electron and proton dosimetry (MeV)
• Also, Ideally suited for the diagnostic energy range (app. 0 HU at 80 - 140 kV tube voltage)
• Customizable: can be molded into arbitrary shapes

CTwater mimics the physical X-ray mass attenuation properties of liquid water regarding its physical density and electron density. It can be used for high-energy photon, electron and proton fields in radiation oncology (MeV), which makes it suitable for the dosimetric evaluation of constancy tests in radiation therapy:

Besides therapeutic energies CTwater is ideally suited for clinical X-ray modalities due to its water-equivalency (0 ± 5 HU) within the full diagnostic energy range of 80 kV to 140 kV tube voltage.

The slabs exhibit long-term stability and can be produced in a large amount with a high degree of homogeneity and mechanical precision.

Custom chamber cavities and adapters for ionization chambers are available upon request.
