Estudio piloto de una auditoría postal dosimétrica para radioterapia en condiciones de referencia

Abstract: En 2019 el Centro Nacional de Dosimetría organizó un estudio piloto de auditoría dosimétrica postal para centros de radioterapia. La auditoría consistió en una verificación de la calibración de haces de fotones de megavoltaje en condiciones de referencia, para lo cual se emplearon dosímetros de luminiscencia estimulada ópticamente (OSL) colocados en un maniquí de agua. Se auditaron 48 haces de energías: 6, 10 y 15 MV con filtro aplanador, y 6 y 10 MV sin filtro aplanador (FFF). Se consideraron aceptables las d… Show more

“…It consists of multiple rows of LEDs of 6500 K temperature color where the dosimeters are exposed for 4 h (Figure 1c). This system is placed at the Spanish Centro Nacional de Dosimetría (CND) and was previously studied by Pujades et al [21] for dosimetric audits of external radiotherapy This system is placed at the Spanish Centro Nacional de Dosimetría (CND) and was previously studied by Pujades et al [21] for dosimetric audits of external radiotherapy beams, where the dose linearity, reproducibility, loss of signal at each reading, energy dependence and fading were characterized. These results were reused for this work, except the part corresponding to the energy dependence factor since, as explained in the following sections, it is included in the calibration coefficient.…”
