Method: Triple channel
10 x 10 cm
2
6 MV field
EBT2 calibration curve (red, bule
and green channels,
16bits/channel)
Consistency map
(non dose
dependent
parameters/artifact
s)
Irradiated EBT2
film (2.25Gy)
TIPS:
Size of calibration
patches at least
10x10 cm
2
0-3 Gy: 8 patches
ADVANTAGES
Corrects for film
thickness differences
Mitigates scanner
lateral dependence
Increases de signal to
noise ratio
Extends dose range
