Insert appropriate DQA-III Phantom into head coil. Verify phantom is inserted into head coil.
Also verify phantom is not rotated within the head coil.
The correct phantom type, position and landmark are all critical to successful operation of
the DQA-II tool.
If there is a failure during the DQA-II tool, the "Actions Required" window will give details as
to the likely reason for the error. If specific recommendations are not available in the
"Actions Required" window, the FE will be pointed to Service Documentation.
