Resumen
En este trabajo final de maestría se presentan las cantidades de influencia en la aceptación específica para aceleradores lineales clínicos Elekta Synergy Platform evaluando: controles de seguridad de la instalación, funcionamiento mecánico y dosimétrico. Gran parte de este trabajo está dirigido a la realización del comisionamiento dosimétrico del equipo antes mencionado reportando los datos exigidos por el sistema de planificación dosimétrica XIO, los datos que se adquieren para fotones de 6 MeV y 15 MeV y para aditamentos como colimadores multiláminas (MLC), cuñas motorizadas y bandejas de PMMA que serán usadas en técnicas Conformacionales (3D-CRT) y de intensidad modulada IMRT, resaltando la influencia de todas las cantidades medidas sobre la dosis entregada. A lo largo de todo el trabajo se valoran las medidas realizadas y se hacen recomendaciones sobre las mismas, el resultado final es verificar que los datos son aptos para realizar el modelaje del acelerador para su posterior uso en los algoritmos de cálculo de dosis y pueda ser usado clínicamente.
Abstract. This master’s degree final project provides the influence quantities involved in the process, related to specific acceptation for Elekta Synergy Platform clinical linear accelerators according to the following items were assessed: setting-up safety control, mechanical operation and dosimetric performance. The mainly purpose of this work is aimed to make the device dosimetric commissioning, in which required data by the dose planning system XIO, are reported. Data are related with 6 MeV and 15 MeV photons and devices like multileaf collimators (MLC), motorized wedges and plates made of PMMA. These parameters are going to be implemented in conformational techniques (3D-CRT) and intensity modulated techniques (IMRT). The influence of all these parameters in released dose is highlighted. Throughout this master’s degree final project, there are a review about the measuring quantities and some recommendations to verify, that the data are adequately modeled for the linear accelerator, and it is ready to be implemented in dose calculation algorithms and in clinical use.
