Systematic Error Correction/Trend Analysis - reference surface capture

SGRT News & Announcements
1

We currently use 3-day Systematic Error Correction/Trend Analysis due to the need to be able to decide which patients could be treated without imaging in the event of one of our two Elekta linacs going down.

Do any departments still use this with SGRT & if so what criteria do you have for capturing a new reference surface capture, ie: first 3 days, rotation under 1 degree?

Thanks

Nick

Hey Nick,

I think this was answered on the previous thread Systematic Error Correction/Trend Analysis - Reference Surface Capture - #2 by marko_laaksomaa

Hopefully others can also respond on the original thread also for more advice and opinions.
