Plastic Water®
Phantom Materials
Plastic Water® is resilient and will not break easily under impact, it is easily machined and is the only calibration material available in 1mm thickness. The advanced casting methods assure void-free product, available in two formulations.
Plastic Water® - the Original
For general calibration work, the original Plastic Water® is the only calibration material which agrees with true water within +0.05%/-0.4% above 4MeV (+/-0.5% from 150keV to 100MeV).
Plastic Water® DT
This improved Dignostic/Therapy formulation is optimized to cover CT energies for radiation planning and dose verification in IMRT. It mimics true water within +/-0.22% from 80keV to 4MeV (+/-0.5% from 50keV to 25MeV).
Size Availability
Although 30 x 30cm slabs are most widely used and therefore considered to be a standard size, Plastic Water® is also available in 20 x 20cm, 25 x 25cm and 40 x 40cm sizes.
Chamber Cavities
For dosimetry measurements, custom cavities are available to accommodate any ion chamber on the market today in slabs of any size and thickness of 2cm and over. Matching positives (plugs) are also available for most ion chamber types. The table shows most of the popular ion chambers. Simply add the appropriate suffix to the model number from the table at left.
