Abstract
Polymer gels are widely used for absorbed dose verification in radiotherapy, providing information about 3D dose distribution in the irradiated volume as well as serving as a simulation phantom, for the observation of radiation induced structural changes, related to gel’s polymerization upon irradiation. Due to high spatial resolution and unable sensitivity through gel’s composition, dosimeter gels is a powerful and precise tool for verification of individual treatment plans especially when high treatment doses are prescribed.The aim of this work was to modify and characterize gel dosimeters that are capable of millimetre scale target/tumour imitation and high dose assessment in small irradiated volume, for their further applications in clinical dosimetry and verification of millimetre scale target treatment procedures using Gamma knife unit.
