Reference Image

Before you begin

Consider this information when you use the Reference Image tool:

The reference image must be in another plane from the main image.
The two images (the main image and the reference image) must be from the same examination and must have the same horizontal landmark, same patient position, and same patient entry.
The viewport image and the Reference Image cannot be a Screen Save, a 3D Rendered Image, or a member of the Combined Images set.
All Reference Image viewports display the same image. You cannot put unique images within separate or different viewports. If you change the image in one Reference Image viewport, all other Reference Image viewports are updated to the same image.
Inverse Video affects both the main image and the Reference Image.
Series Binding should not be applied to the Reference Image.

Use the Reference Image tool to show the image from which the primary image was prescribed in small viewport within the image.
