La dosimetria en pacients sotmesos a PET \u00e9s de vital import\u00e0ncia per a garantir la seguretat del procediment. Tots els equips de radiodiagn\u00f2stic (radiografies, mamografia, TC, PET-CT i SEPT-CT) han de tindre un programa capa\u00e7 d&#8217;avaluar la dosi rebuda pel pacient al final de cada tractament de diagn\u00f2stic. Per aix\u00f2, \u00e9s fonamental el desenvolupament de m\u00e8todes per a poder estimar les dosis rebudes en els \u00f2rgans interns a causa de la radiaci\u00f3 ionitzant impartida i que permeten abordar com reduir aqueixes dosis.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column eplus-wrapper is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<figure class=\" wp-block-image aligncenter size-full is-resized eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"223\" height=\"272\" src=\"https:\/\/iramed.webs.upv.es\/wp-content\/uploads\/2024\/05\/Proyecto_mtlg_O2.png\" alt=\"\" class=\"wp-image-1070\" style=\"width:274px;height:auto\"><\/figure>\n<\/div>\n<\/div>\n\n<div class=\"wp-block-columns eplus-wrapper is-layout-flex wp-container-core-columns-is-layout-7387b849 wp-block-columns-is-layout-flex eplus-styles-uid-28af08\">\n<div class=\"wp-block-column eplus-wrapper is-layout-flow wp-block-column-is-layout-flow\">\n<p class=\"eplus-wrapper wp-block-paragraph\">Per a aix\u00f2 s&#8217;abordaran les seg\u00fcents activitats:<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">1. Desenvolupament de models de dosimetria interna a partir dels kits d&#8217;eines GEANT-GATE i GEANT-GAMOS. Els models inclouen l&#8217;esc\u00e0ner PET i els maniquins matem\u00e0tics i antropom\u00f2rfics, aquests \u00faltims obtinguts a partir de la segmentaci\u00f3 i voxelizaci\u00f3 d&#8217;imatges DICOM CT.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">2. Reconstrucci\u00f3 d&#8217;imatges PET a partir de simulacions de Monte Carlo. Aplicaci\u00f3 a maniquins matem\u00e0tics i antropom\u00f2rfics. Estudi de diferents t\u00e8cniques de reconstrucci\u00f3. Fusi\u00f3 de mapes de dosis i imatges reconstru\u00efdes. Aplicaci\u00f3 a diferents assajos cl\u00ednics.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">3. Comparaci\u00f3 de les imatges generades per Monte Carlo amb imatges d&#8217;assajos cl\u00ednics reals. Caracteritzaci\u00f3 qualitativa i quantitativa d&#8217;errors entre imatges reals i simulades. Estudi de la possible assignaci\u00f3 del mapa de dosi obtingut per simulaci\u00f3 a imatges reals.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">4. Validaci\u00f3 del programa amb detectors MOSFET calibrats. Determinar experimentalment la dosi administrada als maniquins amb els MOSFET i despr\u00e9s comparar els valors calculats per Monte Carlo amb la dosi experimental.<\/p>\n<\/div>\n<\/div>\n\n<figure class=\" wp-block-image aligncenter size-large is-resized eplus-wrapper eplus-styles-uid-5b7ec1\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"176\" src=\"https:\/\/iramed.webs.upv.es\/wp-content\/uploads\/2024\/06\/ade_02_-1024x176.png\" alt=\"\" class=\"wp-image-1347\" style=\"width:1350px;height:auto\" srcset=\"https:\/\/iramed.webs.upv.es\/wp-content\/uploads\/2024\/06\/ade_02_-1024x176.png 1024w, https:\/\/iramed.webs.upv.es\/wp-content\/uploads\/2024\/06\/ade_02_-300x51.png 300w, https:\/\/iramed.webs.upv.es\/wp-content\/uploads\/2024\/06\/ade_02_-768x132.png 768w, https:\/\/iramed.webs.upv.es\/wp-content\/uploads\/2024\/06\/ade_02_-1536x263.png 1536w, https:\/\/iramed.webs.upv.es\/wp-content\/uploads\/2024\/06\/ade_02_-2048x351.png 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\n","protected":false},"excerpt":{"rendered":"<p>O2.
