Truncate at smallest local minimum and maximum values and normalize
to 0 and 1: Truncate lower part of the profile at highest minimum and upper
part of the profile at lowest maximum and then normalize resulting profile to 0
and 1. This approach is very advantageous especially when the leaf openings
vary over a wide range (i.e. the dose varies a lot between the leaf openings).
Use the button to select the normalization mode for the profiles you require.
Relative analyzed leaf width range (%): Width of the averaging region around leaf
center relative to leaf width used to generate the profile. Whenever the profile data or
analysis method is changed, FilmQA
Pro
calculates the leaf opening width values for
the selected beam and leaf index range as shown below.
The color of the depicted
opening depends on the
width and bias of the
specific leaf opening.
Threshold value for
these color changes can
be assigned using the
context menu of the
chart.
