Image Location
Middle-click and drag horizontally to scroll through the images or click to increment
and right-click to decrement an image at a time. Alternatively, you can use the left and
right arrow keys on the keyboard to move through the image set. Scan location is not
available on 3D views.

DFOV
Middle-click the drag horizontally to real-time magnify the image or click to increment
and right-click to decrement the mag factor. The maximum zoom factor (ratio between
acquisition DFOV and actual DFOV) is 8.0. You cannot increase the DFOV beyond
the original value, unless the height of the stack of images (number of images × slice
thickness) is larger than the DFOV. In that case, you can zoom up to the height of the
stack of images (zoom factor < 1.0).
