Thus, polymer gel dosimeters allow a volumetric and not point visualization, as occurs with an ionization chamber. Therefore, this work consisted in evaluating the planning of cancer treatment for the head region using a phantom of the anatomical area filled with gels. Next, tomographic images (computed tomography scan) were generated, which were used for virtual planning and mathematically evaluated. After irradiating the phantom set in a medical linear accelerator, the next step was to submit the simulator to magnetic resonance (MRI) where images were mathematically postprocessed. Thus, uncertainties associated at this stage of the process were evaluated.<\/p>\n<p>[\/vc_column_text]<\/p>\n<p><span class=\"vc_btn2-container vc_btn2-center\"><br \/>\n<a class=\"vc_general vc_btn3 vc_btn3-size-xl vc_btn3-shape-square vc_btn3-style-classic vc_btn3-color-om-accent-color-3 vc_btn3-icon-left\" href=\"https:\/\/metrologia2021.org.br\/wp-content\/uploads\/2021\/10\/CBMRI_208309.pdf\"><span class=\"vc_btn3-inner\"><i class=\"vc_btn3-icon fa fa-file-pdf-o\"><\/i> Download do Artigo<\/span><\/a><br \/>\n<\/span><\/p>\n<p>[vc_text_separator title=&#8221;V\u00cdDEO&#8221; i_icon_fontawesome=&#8221;fa fa-video-camera&#8221; color=&#8221;om-accent-color-3&#8243; add_icon=&#8221;true&#8221;]<br \/>\n<iframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/q-NzWVsY_Sw\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/p>\n","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_text_separator title=&#8221;ARTIGO&#8221; i_icon_fontawesome=&#8221;fa fa-file-pdf-o&#8221; color=&#8221;om-accent-color-3&#8243; add_icon=&#8221;true&#8221;][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]Autor: Jo\u00e3o Henrique Hamann da Silva, Jos\u00e9 Guilherme Pereira Peixoto, Ot\u00e1vio Riani de Oliveira [\/vc_column_text][vc_separator][vc_column_text]Resumo: Dosimeters gels, in particular polymerics&hellip;<\/p>\n<p><a href=\"https:\/\/metrologia2021.org.br\/?p=1995\" class=\"read-more-link\"><span class=\"read-more-icon\"><\/span>Leia mais<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[1],"tags":[],"_links":{"self":[{"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=\/wp\/v2\/posts\/1995"}],"collection":[{"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1995"}],"version-history":[{"count":1,"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=\/wp\/v2\/posts\/1995\/revisions"}],"predecessor-version":[{"id":1996,"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=\/wp\/v2\/posts\/1995\/revisions\/1996"}],"wp:attachment":[{"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1995"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1995"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/metrologia2021.org.br\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1995"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
