FLATNESS AND SYMMETRY ANALYSIS
Click on “Add New Case Object” under
the “Case Object Management” heading.
A drop-down menu will appear and give
you several options. Select “Flatness and
Symmetry Physics QA” (Shown left).
There are two types of objects to select:
‘Flatness and Symmetry Physics QA’ can
hold any number of images to be
analyzed and uses the images directly.
‘Flatness and Symmetry Physics QA
(Dose Map)’ analyzes only a single
image that will be converted into a dose
map. Next, acquire the image by either
reading it from a saved file or scanning it directly.
For the automated image
registration, select the “Fiducial
Tool”, and mark the positions on
the image (Shown right). The
minimum number to determine both
x & y shift and rotation is three
fiducials. When all the fiducials are
marked, select “Flatness and
Symmetry Physics QA” in the case
tree. The isocenter is automatically
fitted to the marked fiducials.
