James it si possible uses CR Karestream to do this test ? I do not have EPID.
Thanks
If your CR outputs DICOM then it should be possible although I have not tried. CR is not a use case in Pylinac.
Hi James, how are you?
I create a code to convert CR into EPID image.
I run the pylinac picket fence. But I think still getting the colimated part and not the irradiated gap.
Attached the files. I think we need to chage the way we irradiate de CR. It has a sensitivity very different from the EPID.
My best regards

Hello Pedro,
Thanks for sharing. It looks like your picket detection is inverted? The tongue and groove lines appear on the darker areas of the image, meaning the brighter areas are the pickets, no?
Analyzing both of your images with a default analysis gives me the correct pickets as far as I can tell. What version of pylinac are you using? Also, you should consider spacing out the “pickets” further apart. See point 2: Picket Fence — pylinac 3.10.0 documentation
Thanks for your feedback.
I am using Pylinac 3.4.0., python 3.9.7 and notebooks [GCC 9.4.0] 6.4.4
