3. “Report Options”, , opens a pop-up window so the user can:
 “Open/Save Document Template” – Loads or saves report settings
 “Show Report Parameters” – Shows or hides report parameter controls
 “Number of Viewed Pages” – Selects fixed or floating number of pages
per page section. Default is set as float.
4. “Print”, sends the report to a printer. Printer selection dialog will appear.
5. “Save”, saves the report as a portable document file, PDF, or as an
image file using one of the many graphic formats.
6. The “Copy” button, copies current chart settings to the reporting tool.
7. “Single Page Output”, selects the number of images displayed on one

7. Other Adjustments
After following the steps and instructions laid out it is very unlikely you will
ever have to use adjustments other than those described in the main section
of this protocol. However in the rare event other adjustments are necessary,
below is a brief overview of adjustments to optimize the analysis.
The analysis tool operates by establishing response profiles along two
specified circular paths around the isocenter. While you may select from a
range of response channels the red channel will provide the sharpest contrast
for radiochromic film images. The analysis tool searches along the circular
paths to find the centers of the beam lines exposed on the film. The search
algorithm seeks the response maxima where the paths cross the beam lines
while avoiding false maxima induced by measurement noise. In general the
larger analysis circle should approach the maximum allowed by the length of
the beam lines exposed on the film and the smaller circle should be 40-60%
of the diameter of the larger one. In most cases the effect of measurement
