Resumen
LEON-MARROQUIN, E.Y. et al. Analysis of the absorption spectra of EBT2 and EBT3 radiochromic films. Rev. mex. ing. bioméd [online]. 2017, vol.38, n.1, pp.363-371. ISSN 2395-9126. https://doi.org/10.17488/rmib.38.1.32.
Objective:
To analyze the net absorption spectra of EBT2 and EBT3 radiochromic films to describe their influence on the behavior of dose-response curves.
Methodology:
The films were irradiated in a linear accelerator of 6 MV. The net absorption spectra were obtained with a UV / VIS spectrophotometer. Dose-response curves were obtained with a scanner, a He-Ne laser and a spectrophotometer.
Results:
The absorption spectrum of the EBT2 shows three focused absorption bands that retain position and increase their intensity as a function of dose, however, this behavior is not observed in EBT3 films. The dose-response curve shows maximum sensitivity using the spectrophotometer, but does not show a defined behavior.
Implications:
Generation of new knowledge for the creation of new optical systems capable of amplifying the responsiveness of the films.
Originality:
Show the correlation between net absorption spectra and their influence on dose-response curves in three different optical systems.
Conclusions:
The behavior of absorption spectra combined with the behavior of the dose-response curves helps to discard the use of optical systems that do not guarantee a reliable clinical use.
