pydicom/rdsr_navigator - getting second instance of X-ray filter

[jrp131191]

Hey there.

I'm using rdsr_navigator which utilises pydicom to read .dcm files. I'm working specifically with Fluoro RDSR's and on certain systems, each Irradiation Event has two X-ray filter instances. One which holds aluminium filtration info and the other holding copper. Im only interested in tbe copper information, however rdsr_navigator is built to find and extract the values out of the first instance it finds within each Irradiation event. This is an issue because on some systems the alu/copper instance can be the first or second instance.

Would anyone happen to know how I can specifically target just the instance containing copper info?

I have tried several things, but neither have turned out to be universal solutions. I did try debugging and stepping through, and it does seem like if there is a solution to this, it probably lies within how pydicom reads in the RDSR rather than how rdsr_navigator utilises it. But I'm also still learning so could be wrong.

TIA.

rdsr_navigator appears to be an orphaned third-party package created by this person which uses pydicom. We only support pydicom itself, not third-party packages.

If you feel comfortable with it, I would take a look at the source for rdsr_navigator and see where it can be improved, or, given the project appears to be abandoned, look for a replacement.
