WATER EQUIVALENT
Virtual Water™ is an ideal alternative to traditional water tanks for performing routine QA checks of a linear accelerator using photon or electron beams
CUSTOM CAVITIES AVAILABLE
Cavities are available in slabs at least 2 cm thick to accommodate most Farmer-type or parallel plate ionization chambers. Optional scribe lines are available for laser alignment.
tested and calibrated
Virtual Water™ is a true water-equivalent material. Slabs from this unique material are exceptionally strong and will not stick together when stacked or stored. Virtual Water™ is not affected by changes in humidity or temperature and does not exhibit charge storage effects, a problem common in other water-equivalent materials. Each production run of Virtual Water™ is tested at an independent calibration laboratory and certified to be within 0.5% of water at photon energies.
setting the standard in water-equivalency
Virtual Water™ slabs are made from water-equivalent material, and are developed to be free of contaminants and air. Many standard sizes and thicknesses are available and custom phantoms are available upon request.
