- •
To analyze the changes in the polarization state caused by the EBT3 films.
- •
The polarization changes are analyzed using linear polarizing films.
- •
A dosimetric method using linear polarizers is developed.
- •
The method is tested using a series of simple regular beams and 21 cases of IMRT.
- •
For a given orientation of the linear polarizer the results are better.
