The Dosimetry Phantom is used for accurately measure absorbed dose and dose rate in Leksell Gamma Knife®. Three adapters for measuring with ionization chamber or other detectors are included. The Dosimetry phantom can also be used to verify dose 3D distributions by means of film dosimetry. The dose distribution position is defined by accurately positioning the films in the phantom using two rods.

The phantom is made of certified therapy grade Solid Water® to respond to radiation in the same way as water.
