3. Click the image to use in the Stereoscopic Image Selection dialog box. If you click
Cancel, the Image Registration window opens for the initially selected image.
4. In the Image Registration window, reticle scale the verification images, then click the
check box for registration method you wish to use.
You can use different methods for each image except for grayscale matching, which you
must use on both images. Refer to Registering Images on page 197.
5. After you have completed the tasks for your registration method in the Image
Registration window, click Calculate Shifts to see the fused image pair.
The stereoscopic registration calculates offset information in 3 dimensions, which is
shown on the Isocenter Shifts tab of the Isocenter Shifts window. The magnitude shown
is the linear distance of the correction in 3D space (the diagonal of the 3 correctional
directions).
6. Click OK in the Isocenter Shifts window when you have the offset you want on the
Isocenter Shifts tab.
If you are doing offline image registration using Setup Intelligence,
open the image pair from the Image Work List dialog box, then
follow steps 2-6 above. Refer to Managing the Review Process – for
Physicians on page 182 and Managing the Review Process – for
Therapists on page 187 for instructions on how to use the Image
Work List dialog box.

In the Image Review window, the Active check box on the Isocenter Offset tab is selected
