Hello,
I am setting up some QA tests for Halcyon using pylinac, specifically the picket fence tests. Halcyon has 2 MLC banks- distal and proximal. Each bank consists of 1cm width leaves, with a 0.5cm offset between the two banks giving effectively 0.5cm leaf width at isocentre.
The pylinac MLC class has presets for each of these MLC banks, each consisting of 60 leaves with 0.5cm width, with an 0.25 cm offset between the centers of proximal and distal.
Am I missing something here? Does this not mean there is an effective leaf width of 0.25cm? Should the widths in each bank not be 1cm?
Thanks
Dominic
