[Rtk-users] CBCT projection values

[Simon Rit]

Dear Atallah,
Please use the mailing list for questions that can interest other users. 
The values in the his files are the raw projections after flat field 
correction. The value of I0 is not provided by Elekta. RTK currently 
uses a fixed I0 equal to 65535 but this is probably not accurate.
Best regards,
Simon
