The remaining slice panes display 2D images of the individual slice planes as well as maximum intensity projections (MIP). The lower right pane controls the axial plane, the lower center pane controls the coronal plane, and the lower left pane controls the sagittal plane. The sagittal plane and its controls can be seen in Figure 2.5.

Each slice pane contains a mode UI located in the bottom of the pane, which contains the modes Slice mode, Slab mode, and MIP mode. This mode UI can be hidden or expanded by clicking the bar on the bottom. To change the mode, click the corresponding radiobutton. The slider configuration below the radiobuttons will change.

Slice mode uses a single slider to specify which slice along the axis to view. The user can change the slice in four ways: move the slice slider, enter a value in the entry box to the right of the slider and hit the Enter key, use the mouse scroll wheel to view the previous/next slice, or use the < and > keys to scroll through slices.

For Slab mode, a range widget will appear below the radiobuttons that allow the user to specify a minimum and maximum slice value. The resulting image will be a maximum intensity projection of just the slab of slices specified with the range widget. Users can click on the minimum or maximum sliders to change their values or click on the red bar between the two sliders. When dragging the red bar, the range width will remain the same and the minimum and maximum sliders will move in sync.

Clicking the MIP mode removes the sliders and shows the maximum intensity projection of all of the slices. This would be equivalent to using the Slab mode and setting the minimum and maximum to zero and the maximum slice respectively.
