Options: Provides a menu of options to customize the calibration table
The dose values can be entered manually from the keyboard or copied and pasted from
a table of values. From the IMRT and RapidArc examples installed with FilmQA
™
Pro,
the doses, in cGy, are embedded in the names of the image files. The dose values can
be entered in any order, since, by default, once the table is full, the dose
values/responses are sorted in reverse order depending on the responses in the red
color (i.e. lower response values are associated with higher dose). Right click the Color
Channel Synchronization icon, just below the table to select a choice for
synchronizing the dose values with the response values, or to turn off the dose-
response synchronization. Note: Doses and/or response values could also be entered
by copying and pasting from a table. There are files Exposure.txt in each of the folders:
Example EBT2 IMRT and Example EBT3 Rapid Arc containing the example images.
For convenience open the appropriate txt file and copy and paste the doses into the
calibration table.
The image below shows a completed calibration (the EBT2 IMRT example). The mosaic
image and user-selected ROIs are shown in the image panel (center section). The film
evaluation panel (right
section) displays
tabulated and graphical
calibration data for
each color channel
along with the user-
selected fitting function
and coefficients relating
measured film
response to dose.
