Water equivalent dosimetry

For clinics that base all dosimetry on water and want to stay consistent, Delta4 Phantom Plastic Water is the system of choice.

The material has been chosen for its ability to simulate water within a wide energy range.

With Delta4 Phantom+ Plastic Water®, you can now carry out QA without scaling artifacts due to density and correct scatter from materials with higher densities.

Highest accuracy in dose determination

Water equivalence in diagnostic and therapy range
