Picket Fence

Dear all,

I did a picket fence using Eleckta and Siemens equipment. When I compared the results with doselab, I found that the Max Error was lower with pylinac.Is this due to the use of unsupported varian or halcion MLC?

I suspect that using an unsupported MLC will affect the leaf number.

Is there a possibility of DPI or SID?

Thanks

Hi,
you can create a custom MLC configuration: https://pylinac.readthedocs.io/en/latest/picketfence.html#customizing-mlcs
Also if you want to better understand der difference between doselab and pylinac there are a lot of images for benchmarking:
