The purpose of this study was to evaluate dependence of MAGICA polymer gel dosimeter 1/T2 on different electron energies as well as on different mean dose rates for a standard clinically used Linear accelerator. A calibration curve (in the linear region) based on 12 dosimeters (11 irradiated and one background) was obtained for 6MeV electron beam. Dose rate of dependence was studied in 10MeV el...

Prokrustes hat allerdings, schlau wie er ist (er stammt ja schließlich aus einer uralten Räuberfamilie), inzwischen den Wechselapparat gegen den eines anderen Herstellers ausgetauscht. Als Alexeus nachzählt, traut er seinen Augen nicht: Prokrustes hat unseren armen Handlungsreisenden um die Hälfte seiner Bits betrogen (gemäß der Devise: Wer wird denn eine Bank überfallen, wenn das Gründen und B...

after the German collapse in its second edition of 1919. Here he argued from the point of view of bourgeois European culture in favour of saving civilization by a union of European states, including all those other nations whose culture derives directly or indirectly from Europe's. Nicolai's Eurocentrism even went so far that he declared genocide to be understandable in the case of a Mongolian ...

BACKGROUND Radiation-sensitive polymer gels are among the most promising three-dimensional dose verification tools and tissue-like phantom developed to date. OBJECTIVE The aim of this study is an investigating of percentage depth dose enhancement within the gel medium with used of conformal distribution gold nanoparticle as contrast agents by high atomic number material. METHODS In this wor...

Introduction: Bismuth-based nanoparticles having high atomic number and electron density, besides of being utilized as CT contrast agent, stand as a strongly proposed method for dose enhancement in radiotherapy. Embedded nanoparticle in polymer gel dosimeter poses the first step to assess the dose enhancement capability in nanoparticles. To this end, MAGICA gel dosimeter, whic...

Background: Gold nanoparticles (GNPs) are among the most promising radiosensitive materials in radiotherapy. Studying the effective sensitizing factors such as nanoparticle size, concentration, surface features, radiation energy and cell type can help to optimize the effect and possible clinical application of GNPs in radiation therapy. In this study, the radiation sensitive polymer gel was use...

background: the purpose of this study was to evaluate the dependency of magica polymer gel dosimeter response (r2) on different electron energies as well as on different mean dose rate for a standard clinically used linear accelerator. materials and methods: the sensitivity of the dosimeter was represented by the slope of calibration curve in the linear region measured for each modality. a cali...
