Depth dose calibration phantom: item catalogue number: PH-3-DTH

Recent design - see the photographs above.



Height: 345 mm

Inner diameter of the main part available for irradiation: 60 mm

Height of the main part available for irradiation: 280 mm

Width max (lower lid: stand): 100 mm


Polymer gel volume: approximately 890 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.



A hint

For the Depth dose calibration of a polymer gel dosimeter, this phantom should be filled in with a polymer gel dosimeter and placed in a water phantom to be irradiated. The user should place it there such that it is 1 mm above the water level (the upper cap with a small transparent window should be 1 mm above the water level). See also how the data from scanning of the phantom are processed with the polyGeVero® software: Software for 3D dosimetry/Calibration Workspace/Depth dose calibration (polyGeVero®software: item catalogue number: S-2POLY-1).
