The general layout will consist of 3 2D-Windows placed in the order:
A - shows one slice of the fixed image in chosen plane
B - shows the same slice of the moving image
C - shows the result of MovingImage <OP> FixedImage with default <OP> set to subtraction
all windows allow the mouse-scroll interaction for traversing the slices.
The associated View provides the FixedImage and the MovingImage ( set through a drop-down box ), the operation used in the render window C and also the reconstruction plane ( axial, coronal, sagittal) which is shown in ALL windows.
