Catphan504 Slice Thickness

Hello,

I have seen the reported slice thickness for our linacs consistently on the small size (around 0.3-0.5 cm different). Has anyone else had similar results, or is there something I can try to do differently on the scan parameters? This has happened on C-Series and on TrueBeam.

Thanks!

Landon,
If you want to verify the reported value is valid, you could plot an arbitrary profile of a single slice along the ramp and manually determine the FWHM of the profile. You could do this pretty easily in Eclipse as a quick and dirty hack. Just a thought.
