Viewing Data

General Information

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

Caution

Orientation



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.

  • Horizontally, to flip the image right/left

Presets

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%.
No.

Explanation

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.
