Detecting BB center coordinate for kv images

[tsengt01]

Hello,

I would like to know if it is possible to use any of the module in pylinac to retract the BB center coordinate for planar kv (Varian OBI) images just like what can be done for EPID images with the Winston-Lutz test?

Thank you so much in advance.

"retract the BB center"? If you mean "extract", as in, find the BB center as part of a Winston-Lutz test, yes. See this section: https://pylinac.readthedocs.io/en/latest/winston_lutz.html#kv-analysis-imaging-only-iso-evaluation
