Effect of inorganic salts and matrix crosslinking on the dose response of polymer gel dosimeters based on acrylamide
(Elsevier Ltd, 2018-07-17)
The use of additives in polymer gel dosimeters to enhance their sensitivity or to improve their performance is of
great importance for their application in radiomedicine. Inorganic salts have been used as additives with ...
Polymer gel dosimeter based on itaconic acid
(Elsevier, 2015-07)
A new polymeric dosimeter based on itaconic acid and N, N’-methylenebisacrylamide was studied. The preparation method, compositions of monomer and crosslinking agent and the presence of oxygen in the dosimetric system were ...
Avaliação de dose periférica em um caso de IMRT de cabeça e pescoço utilizando filmes radiocrômicos
(Universidade Tecnológica Federal do ParanáCuritibaBrasilTecnologia em RadiologiaUTFPR, 2017-03-08)
The objective of this work is to collect and evaluate the peripheral doses in IMRT treatment in the head and neck region with the use of radiochromic films. For this it was necessary to simulate a real IMRT treatment using ...
