Viewing Data

General Information

View functions provide basic image manipulation options. Changes are applied to the current image set and its reconstructions.



A human figure appears in the lower left corner of each view to indicate the orientation of the image.

Other relevant orientation indicators appear in each view, including: H (head), F (foot), L (left), R (right), A (anterior) and P (posterior).

2D Orientation

This symbol is shown when displaying 2D images.

Basic View Buttons

The basic viewing buttons are always available in DICOM Viewer.



Scroll: Drag:

  • To the right or down, to move forward through the set
  • To the left or up, to move backwards through the set

Zoom: Drag:

  • Up to zoom out
  • Down to zoom in

Pan: Drag the image to the desired position or press the image to center the image at that point.

Add View: Opens reconstruction selection.

Reconstructions: Opens reconstruction selection.

Maximize/Minimize: Maximizes/minimizes the selected image.

Close Image: Closes the selected view.

Scroll Arrows: Arrows within the view for scrolling through image slices.

View Functions



Reset: Resets all slices to the original viewing settings.

Linked View: Links multiple image sets on the screen.

Presets: Select CT windowing presets.

Windowing: Adjust the brightness (up and down) and contrast (left and right).

Slices: Adjust the number of slices displayed.

Thickness: adjust slice thickness.

Align: Allows you to adjust the orientation of scan data.

Flip: 2D only (X-rays). Drag across the image you wish to move:

  • Vertically, to flip the image up/down
  • Horizontally, to flip the image right/left

Screenshot: Takes a screenshot of current screen.


You can choose pre-set windowing settings for CT image sets which are optimized by Brainlab to display particular structures such as bone, lung or soft tissue. To do this, press Presets to see a list of available optimizations.

Thickness Function

The Thickness function is only available for original slices if:

  • The slice distance is the same over the whole image set,
  • The maximum slice distance is 2 mm, and
  • The maximum difference between slice distance and slice thickness does not exceed 10%.


Slider bar for adjusting slice thickness. The thickness range depends on the distance between slices and cannot exceed a maximum of 6 mm total thickness.

The averaged thickness is indicated in the header (in front of AVERAGE).

A box indicates the thickness of the averaged area.

Linked View Requirements

Linked View links multiple image sets. Any actions performed on one set (e.g., scrolling or panning), are also performed on the linked views.

To use Linked View, the images/image sets must either:

  • Be part of the same image set or reconstruction, or
  • Be fused (through Brainlab software or the scanner)
