| Display of Volumetric Image Data: The interface for adjusting Window, Level, Threshold, Color LUT and other parameters that control the display of volume image data in the scene is found in the "Volumes Module". To access this interface, either select the Volumes icon (shown at the left) from Slicer's Toolbar, or choose the module from the Toolbar's Modules Menu; then open the module's "Display" panel.
| Model Display: Display options for geometric data like VTK models and FreeSurfer surfaces are found in the "Models module". To adjust parameters such as Color, Transparency, and Clipping, select the Models icon (shown at the left) from Slicer's Toolbar, or select the module from the Toolbar's Modules Menu; then open the module's "Display" panel.
| Multiple Layers in each Slice Viewer: Each Slice Viewer supports three layers: (Foreground or FG, Background or BG, and Label or L) that can be viewed separately, or blended together in a customizable fashion. When a new scalar volume is loaded, it is automatically displayed in the BG layer. When a new label map is loaded, it is automatically loaded into the L layer. The contents of these layers can be selectively changed in any Slice Viewer's control panel.
| Fiducial Point Display: Fiducials are useful tools employed in many Slicer analysis modules. Their visual representation and display can be adjusted in the "Annotations module". Interactive placing of fiducial points can be accomplished by selecting the Place Fiducials tool from Slicer's Toolbar.
| Volume Rendering: Slicer's Volume Rendering Module provides advanced tools for toggling volume rendering of datasets. Hardware accelerated volume rendering with nVidia drivers is available on Linux and Windows platforms. The module permits selection of preset transfer functions to colorize and set opacity of data in a task-appropriate way, and tools to customize the transfer functions that specify these parameters.
| Layouts: Slicer provides a variety of layout options. These may be selected from the Choose Layout menubutton in Slicer's main Toolbar (shown at the left). Icons and names of available options are shown below.
| Crosshair Options: Crosshairs can be customized by selecting among options available from the Crosshairs menubutton (shown at the left) in Slicer's Toolbar. Here, Navigation and Slice Intersection modes can be toggled, and different crosshair styles can be selected.
| Cross-referencing Across Viewers: It is often useful to index the same RAS position in multiple slice viewers. This cross-referencing interaction mode can be accomplished by holding down the "Shift-Key" while positioning the mouse inside any Slice Viewer.
| Data Probe: The Data Probe is an interactive tool that returns information available at the RAS position addressed by the mouse pointer. Data Probe output is visible in the bottom of the main GUI panel.
| Capturing & Restoring Scene Views: Scene Views are particular "states" of the MRML scene (including datasets, display parameters, annotations, layout, camera configurations etc.). Scene views provide a useful mechanism to capture or communicate interesting visual presentations of complicated data. The icons shown at the left are found in Slicer's Toolbar. The top-most icon is used to capture a "view" of the scene configuration and save it with a unique name. That "view" can be restored at a later time by selecting the Scene View Menubutton, shown at the lower left. Slicer's Scene Views Module offers an advanced interface for capturing, browsing and restoring Scene Views. Scene Views will be saved with your scene.
| Screen Captures: The Screen Capture icon shown at the left is found in Slicer's "Capture" Toolbar. Use this tool select which Viewers you wish to capture, and to save them to an image file.
