Much of the complex medical physics work requires radiation dose delivery, which dosimeters to accurately measure three-dimensional distribution with good spatial resolution. MAGIC-f polymer gel is one emerging new widely used in research. The purpose this study was present an overview dosimetry, using gel, including its composition, manufacture, imaging, calibration, and application In review,...

In order to decrease the negative influence of oxygen to the response of PAG dosimeters THPC has been added to the gel in the role of scavenger. Apart from the decreased influence of oxygen, THPC also influences other properties of gel dosimeters. This study examines these influences and their quantification. Previous studies have shown that increasing the concentration of THPC causes a decreas...

Purpose In our proton beam therapy center, we use imaging plates (IP) for dose verification of field matching in irradiation (called patch-field technique). this study, a polymer gel dosimeter, which can perform three- dimensional distribution measurement, was used as new tool the patch method corresponding to rectangular irradiation. Method The results measurements PAGAT dosimeter irradiate tw...

background: over recent decades, modern protocols of external beam radio¬therapy and radiation techniques such as intensity-modulated radiotherapy (imrt) have been developed. these methods are extremely sensitive to errors in treatment delivery, so that it is essential to apply a high resolution 3d dosimetry system that has high sensitivity and is capable of measuring and verifying the complex ...

introduction: despite the fact that the clinical implementation of polymer gel dosimetry has been facilitated after the introduction of normoxic gels, there are still complications in its clinical routine use that are under investigation. in the current work, the feasibility of using a normoxic polymer gel dosimeter named magica has been investigated for use in our clinical brachytherapy applic...
