Acrylic and water-equivalent RW3 slab phantoms with chamber adaptation plates for therapy dosimetry

  • Make it possible to perform monitor calibrations and depth dose measurements in a solid state phantom
  • Suitable for high energy photon and electron dosimetry
  • Make it possible to vary the measuring depth up to 30 cm in increments of 1 mm
  • Made of acrylic material or water-equivalent RW3 material (Goettingen White Water) with thickness tolerance of ± 0.1 mm

The acrylic slab phantom is designed for the use with photon radiation in the range from 70 kV up to 50 MV and for electron radiation from 1 MeV up to 50 MeV. The RW3 phantom is water-equivalent in the energy ranges from 60Co to
25 MV photons and from 4 MeV to 25 MeV electrons. The phantoms are used for monitor calibration and quality assurance measurements. Depth dose measurements are made by varying the measuring depth. To provide for backscatter, slabs are placed below the radiation   detector. The slab phantoms each consist of 1 plate 1 mm thick, 2 plates each 2 mm thick, 1 plate 5 mm thick and 29 plates each 10 mm thick. This combination makes it possible to vary the measuring depth in increments of 1 mm. The size of the complete phantoms is 30 cm x 30 cm x 30 cm. Adapter plates for a number of detector types are available for both phantoms. Each plate is precisely machined for a thickness tolerance of only
± 0.1 mm.
