Dose distribution phantom 2: item catalogue number: PH-6-DD2
Height: 170 mm (+ 10 mm: a filler plug)
Inner diameter of the main part available for irradiation: 80 mm
Height of the main part available for irradiation: 90 mm
Width max (lower lid: stand): 120 mm
Polymer gel volume: approximately 650 cm3
Some features of the phantoms:
- Phantoms (new design) equipped with a pressure-compensating valve*.
- Very easy to operate.
- Very easy to clean.
- For multiple use.
- The construction enables tight closure and the separation of a polymer gel dosimeter composition from oxygen.
- Transparent walls for observation of the irradiation effects in a polymer gel dosimeter.
- They are made of plastic. They can be scanned with MRI, CT or OCT.
*The pressure-compensating valve has been designed to compensate for changes of pressure inside a polymer gel dosimeter during and after the filling up of the phantoms, as well as during solidification of the gel dosimeter. Some polymer gel might shrink slightly during the solidification, storage or under ionising irradiation. The valve is intended to improve the performance of the dosimeters. The valve can be filled with an inert gas before or after the filling up of the phantom with a gel dosimeter composition (not obligatory). It can also be dismantled, if pressure compensation is not necessary.
The phantom is designed for external beam irradiation. After scanning an irradiated polymer gel dosimeter in the phantom with the chosen technique (CT, MRI, OCT or Ultrasonography), the data can be calculated with the aid of the polyGeVero®software (item catalogue number: S-2POLY-1).
