6.5 Roving Window
The roving window utility allows for quality control of the registration process. The following
describes how to use this aspect of the Change feature.
On the Change page:
1.
In the slices section, with the mouse pointer on a slice image, click and hold the right
mouse button. Note: The user may zoom the images prior to performing this step using
the Zoom page control.
2. A rectangular “window” appears containing slice data as follows.
a. If the user performed step 1) on a slice in the left-most column of slices (usually a
stress dataset), the window contains slice data from the adjacent slice in the
middle column of slices (can be a rest or stress dataset).
b. If the user performed step 1) on a slice in the middle column of slices (stress or rest
dataset), the window contains slice data form the adjacent slice in the left-most
column of slices (usually a stress dataset).
c. If the user performed step 1) on a slice in the right-most column of slices (the
Change slices), the window contains slice data from the corresponding slice in the
left-most column of images (usually a stress dataset).
3. While holding the right mouse button the user can drag the window in that slice area and
verify correct registration of the slices by positioning the window over the underlying slice
data.
