EP-1771: Evaluation Of Skin Dose Changes Using Tld For Head And Neck Patients Treated With Helicaltomotherapy
Year: 2018
Type: conference-abstract
Abstract: S950ESTRO 37(0.4-0.8)% for the green and red channels, and (1.0-2.8)% for the blue one.This is due to the blue curve general flatness, giving a higher error value.The rational formula can be inverted for each of the three RGB colors to provide three dose values with their propagated error, that can be used to give a final more accurate dose value in all the full range. ConclusionFrom this work emerges that the rational function fits well at all low, medium and high doses: it's so usable both in the recommended dose range values and at higher ones.A consistent dose response was thus observed in EBT3 films, no deviation from the known response curves is shown.However, some difference in the recorded pixel values was detected using two different scanners, probably due to their dissimilar light source and sensor system.
