To demonstrate the dose map calculation,
another case object will be added to the
example from the previous section, Calibration.
Specifically the example adds a Dose Map
object to the “Film Calibration (mosaic)” object.
Begin by clicking “Add New Case Object” under
the Case Object Management heading in the
Case Data Selector window. From the drop-
down menu select “Dose Map (Single Scan)”
and when the dose map object appears in the
case tree click “+” to expand the heading. Then
right click “Data – Dose Film (Empty)” and
import the IMRT image by choosing “Open
Image ‘Dose Film’ from File”. Navigate to
Program Files/Ashland Specialty Materials/Film
QA Pro 2013/Image/Example EBT2 IMRT and open the “IMRT Composite” image.
FilmQA
™
Pro can open various image formats including “bmp”, “tiff”, “gif”, “jpeg”, “png”
and “fits”, but for dosimetry the “tiff” format should be the one used. FilmQA
™
Pro also
recognizes images in DICOM format
files. To use a DICOM file, select
“Open Image ‘Dose Film’ from DICOM
File”. IMRT image in the example is
from a head-and-neck treatment plan
and is a composite containing all seven
fields. Note: A dose map image may
also be generated directly by scanning an application film.
