Values of MTF50% for CBCT with Pylinac v2.3.2

Dear users:
I have found rare values for MTF50% when a Catphan 504 CBCT is analyzed using Pylinac v2.3.2. Same CBCT is analyzed with Pylinac version 2.2.6 and different MTF50% is given. I enclose screen shots showing this comparion btw Pyllnac versions
Please, have someone noticied this issue?.

Comments and suggestions will be very appreciated
Thanks so much


Pylinac was previously reporting lines/mm and has been corrected to report line pairs/mm. See:
