In Checkerboard mode, the reference and input data set(s) are arrayed in a pattern of alternating squares, resembling a checkerboard. This mode is especially useful when checking image registration.

Getting There

Using the tool

Upon selection of the Checkerboard Tool, the display of the coronal, sagittal, and transverse windows is automatically updated.

Both the Input 1 and Input 2 data sets (if present) are displayed in the same squares of the checkerboard. To return to normal viewing, select Navigation in the Tools menu.
