dc.description.abstractLa impresión 3D de bolus en radioterapia es una nueva tecnología que se desea implementar en el Instituto Nacional de Cancerología, permitiéndole al paciente un mejor tratamiento contra el cáncer. El objetivo de este estudio consistió en describir y evaluar la implementación del bolus impreso 3D en el entorno clínico, para ello se evaluaron las propiedades dosimétricas mediante el estudio de los porcentajes de dosis en profundidad y los porcentajes laterales de dosis de los materiales ABS y PLA en diversos porcentajes de impresión, 20\%, 40\% y 60\%. Esta caracterización se realizó para la radioterapia externa con un haz fotones, electrones y braquiterapia de alta tasa de dosis con una fuente de Iridio-192. A partir de los resultados obtenidos se puede concluir que para el caso de fotones el porcentaje de impresión más similar a la parafina para ABS, es del 60\% mientras que para PLA es del 40\%. Para el caso de electrones tanto para ABS como para PLA, se recomienda un porcentaje de impresión mayor al 80\% y finalmente para el caso de la braquiterapia de alta tasa de dosis con Iridio 192, se recomienda un porcentaje de impresión del 60\% tanto para ABS como para PLA.

The objective of this study was to describe and evaluate the implementation of the 3D printed bolus in the clinical environment, for which the dosimetric properties were evaluated by studying the depth dose percentages and the lateral dose percentages of ABS and PLA materials. in various printing percentages, 20\%, 40\% and 60\%. This characterization was performed for external beam radiotherapy with a photon-electron beam and high-dose-rate brachytherapy with an Iridium-192 source. From the results obtained, it can be concluded that in the case of photons, the printing percentage most similar to paraffin for ABS is 60\% while for PLA it is 40\%. In the case of electrons, both for ABS and PLA, an impression percentage greater than 80\% is recommended and finally, in the case of high dose rate brachytherapy with Iridium 192, an impression percentage of 60\% is recommended. for both ABS and PLA.eng

dc.description.methodsPara el desarrollo del proyecto se utilizó la impresora 3D ZORTRAX M300 PLUS ( Ver figura 2-7) que posee la capacidad de imprimir en 3D modelos grandes, con un área de impresión de 30 x 30 x 30 cm3. Funciona con la tecnología LPD (Deposición de plástico de capa), que consiste en depositar material fundido capa por capa en la plataforma de construcción, siendo esta versión de modelado de deposición fundida (FDM), que garantiza resultados de la más alta calidad y bajo mantenimiento. Zortrax M300 Plus imprime en 3D con filamentos avanzados y de tipo flexible tales como, Z-ABS, Z-PLA, Z-GLASS, Z-ESD, Z-PLA Pro, ZASA Pro, entre otros.spa
