3.3.5.1 Top Hat Fluence
The Top Hat computational results displays a value for the Max and Min fluence observed in a
Top Hat beam’s energy profile. This result is affected by which Top Hat method is being
employed. The Top Hat Fluence Pass/Fail edit control items are applied to both the Max and
Min fluence results. It is anticipated that the Minimum Pass/Fail limit is primarily applicable to
the Min results, and that the Maximum Pass/Fail limit is primarily applied to the Max results.
Thus an energy intensity range can define the acceptable limits of the Top Hat beam’s working
surface area.
