I am not sure what you mean by "commissioning TBI". As far as I know the commissioning refers to the characteristics of the LINAC you will be using and not to the TBI method in itself

If you are thinking about in vivo dosimetry, you can find several papers on the use of EBT Gafchromic films Look for instance at the following:

Thank you very much sir

Any studies regarding to "TBI data acquisition by Gafchromic  EBT Films" ?
