Doing tests on Elekta linacs with QAserver

Hi there! This page contains some notes about doing interesting tests on Elekta linacs with QAserver.

This is the main page:

QAserver

The notes are part of QAserver’s documentation, so go read the rest too: documentation. It’s not a lot, but then it’s the little things in life that are of value, large things just cast a big dark shadow on everything and give you an even bigger headache.
