Question about picket fence

[Jim Royal]

Hello,

I just discovered your AssuranceQA web software.  Thank you.  With the picket fence test, is there a suggested picket fence shape, such as the Test 0.2 from the RapidArc QA files from myvarian?

Or can I use a picket shape with  1 cm wide gaps that step across the field?

Thanks,

Jim

The Varian picket fence test that comes with the rapidarc files are the best fit for pylinac's picket fence analysis. Pickets wider than a few mm are not guaranteed to work. If anyone performs these wide gap tests I'd be more than happy to try and make pylinac compatible with those image types. Upload your images privately here.
