| description | Dosimetry by polymer gel associated with magnetic resonance imaging (MRI) is a promising technique for three-dimensional dose determination in radiotherapy. Understanding the effects of the interaction of radiation with the materials that make up the dosimetric solution and the mechanisms of the polymerization process are fundamental. Thus, studies associated with polymer gel dosimetry have been widely developed. The awakening to this type of work is due to the fact that dosimetry by polymer gel is a tool that allows, for example, the three-dimensional analysis of the dose distribution in a given volume. In this article, a literary review was carried out for a better understanding of the mechanisms responsible for the polymerization process of the dosimeter gel. Then, following the protocol presented in TRS 398, samples of the nPAG type dosimeter gel were irradiated in a medical linear accelerator with 6MeV X-ray beam energy. The response curve of these samples was obtained through the statistical analysis of magnetic resonance images. |
