Dose Course 2018_Flipping book

Method: Triple channel

EBT2 calibration curve (red, bule and green channels, 16bits/channel)

Irradiated EBT2 film (2.25Gy)

10 x 10 cm 2 6 MV field

TIPS:

Consistency map (non dose dependent parameters/artifact s)

Size of calibration patches at least 10x10 cm 2

ADVANTAGES

Corrects for film thickness differences

0-3 Gy: 8 patches

Mitigates scanner lateral dependence

Increases de signal to noise ratio
