Effect of scanning parameters on dose-response of radiochromic films irradiated with photon and electron beams.

Proper dosimetry settings are crucial in radiotherapy to ensure accurate radiation dose delivery. This work evaluated scanning parameters as affecting factors in reading the dose-response of EBT2 and EBT3 radiochromic films (RCFs) irradiated with clinical photon and electron beams. The RCFs were digitised using Epson Expression 10000XL flatbed scanner and image analyses of net optical density () were conducted using five scanning parameters i.
