2.8 Stereotactic Planning and Localization
General Information
With the localization planning task, you can assign the localizer to the selected image set andperform stereotactic localization. Stereotactic localization provides a headring-specific coordinatesystem in which it is possible to calculate the arc settings for a planned trajectory.
Stereotactic localization should be performed prior to planning trajectories or objects inthe image set, as well as prior to performing image fusion, to ensure consistentvisualization of planning content in all views.
Hardware
Carefully check the accuracy of your localization hardware on a regular basis.
Localization is only possible in combination with fully functional hardware. If the localizerhardware is defective or damaged, or if the rod geometry is incorrect, this can either causelocalization to fail, or lead to incorrect results.
Supported Images
Imaging modalities that cause image distortions (e.g., MR EPI data sets) or improper rod markerrepresentation (due to poor contrast) cannot be properly localized.
General Workflow
Step
1. Select the image set scanned with the localizer.
2. Select your chosen localizer from the toolbar.Localization starts automatically.
For reviewing and correcting localization results, follow these steps:
Step
1. Review each slice with regards to rod detection definition.This applies to all slices, e.g., green, yellow and red.In the case that a rod is not detected correctly, manually correct its position.In the case that a rod is not detected at all, use Add Rod to position it manually.
2. Use Ignore Slice for slices outside the localizable range (i.e., for slices outside thelocalizer geometry, showing none or insufficient number of rods).
3. Select Localize after performing the adjustments in order to get a new localizationresult based on verified and corrected rod detections.
4. Continue using Ignore Slice to exclude single slices, containing e.g., air bubbles.However, do not use Ignore Slice to correct image distortions, artifacts or defectivelocalizer hardware with e.g., loose or bent plates.
NOTE: If too many slices have been ignored (e.g., due to defective hardware or scanningartifacts), localization cannot be calculated. In this case, the localizer needs to be repaired and/ora new scan must be acquired.

Failed Localization
If no slices could be localized:
Step
1. Check the assigned localizer.
2. If the wrong localizer has been selected, assign the correct localizer and repeatlocalization.
3. Start the steps according to the general workflow.

2.8.1 Localizing the Image Set
General Information
The first step in performing localization is localizer assignment. This provides a frame of referencefor the slice set.
How to Localize the Image Set
Step
1. Select the image data from Content Manager.
2.
Select Frame Planning.
3.Select Localization.The screen changes to localization mode.
4.
Select your localizer from the drop down menu. Make sure you choose the same combi-nation that was used during scanning.Localizing starts automatically.
You must select the correct localizer for localization. If an in-correct localizer is selected, all slices might be successfullylocalized, however, the subsequent coordinate system, basedon a combination of localizer, headring and arc system, will beincorrect.

Screen Explanation
No. View Explanation
① Catalog
Depending on the localization result, the color of the slices varies:• Green: Slice successfully localized.• Yellow: Slice has been localized, but precision is low due to one or
more misplaced rod markers, poor image quality or an inaccurate lo-calizer geometry.
• Red: Slice could not be localized. Several reasons are possible,e.g., not enough rods detected.
② Main
Shows the slice currently selected in the catalog view and whether theimage slice could be localized (upper left corner).Rod marker colors:• Green: Localized rod markers.• Yellow: Rod markers with poorest localization result.• Blue: Indicates that some, but not all rod markers could be localized.
③ Functions area Use the functions to modify the localization as needed.
④Magnified axialview
Shows a magnified view of the area indicated by the white dotted cir-cle in the main view. Use this view to better examine the position of aparticular rod marker. To magnify another area, click on a different rodmarker.
⑤ 3D
3D view of all detected rod markers together with the expected localiz-er geometry.Use this view to verify the localizer rod geometry and identify sliceswith misplaced rod markers. Rod markers should reconstruct in astraight line.
Localization Example
50 Software User Guide Rev. 1.0 Cranial Trajectory Planning Ver. 2.0
Verifying Localization
Carefully visually verify the contents of each view, in order to ensure that localization has beensuccessful.
Verify that every slice has been localized correctly, (e.g., using the 3D view). Even if thesoftware indicates that a slice has been localized successfully (displayed in green in thecatalog view) the slice must be checked. For example, the arrangement of the rods may becorrect, but due to artefacts, the rod geometry as a whole may be displaced.
Rod Marker Positions
If a gantry tilt is used for CT scans, or if a scan is oblique (e.g., MR), the image slices must stillintersect the rods of the localizer at a perpendicular angle. Refer to the scanning instructions foracceptable gantry tilt or oblique angles.
How to Adjust the Threshold
①Figure 23
Step
1. Adjust the Threshold by using the slider ①. If necessary, adjust the threshold value usedto detect rod markers.

2.8.4 Ignoring Slices
When to Ignore Slices
The Ignore Slice function allows you to exclude slices with insufficient rod marker definition fromthe localization calculation. This might be used for slices where it is not possible to manuallyposition rod markers.When you ignore such slices, the slices are no longer considered for localization calculation,however they keep their relative position within the image set.The Ignore Slice function does not delete slices from the localization.NOTE: The Ignore Slice function is contraindicated if you are using scans during which thepatient moved, or if image sets show distortions, or for correction of defective localizer hardwarecontaining impurities, (e.g., many air bubbles).
Ignored slices of a data set may lead to an inaccurate localization as a result of not usingall available rod marker information for localization. The user must make sure to localize asmany slices as possible so that the localization precision of each slice is as high aspossible. Only ignore slices that cannot be localized manually.
Localizer Hardware
Localization is only possible in combination with reliable hardware. If the localizerhardware is defective due to, for example, air bubbles in the rods, localization will not bepossible.
How to Ignore Single Slices
Step
1. Select the slice in the catalog overview.
2. Click Ignore Slice.The localization result is updated and the slice color in the catalog overview changes fromred/yellow to gray.
How to Ignore Multiple Consecutive (Intermediate) Slices
Step
1. Press SHIFT on the keyboard and select the first slice to be ignored.Keeping SHIFT pressed, select another slice to be ignored or use a double click on aslice to select all neighbored slices showing the same color.
2. Click Ignore Slice. The selected slices and all those in between are ignored from the lo-calization.The localization result is updated and the slice color in the catalog overview changes fromred/yellow to gray.

2.8.5 Adding and Positioning Rod Markers
When to Add or Position Rod Markers
You can manually add rod markers to the slice if the software is not able to localize a slicebecause an insufficient number of rod markers have been detected (due to e.g., bubbles in therods, unfavorable scan parameters, or T1/T2 weighting).You can reposition rod markers in the selected image slice if a slice cannot be localized due tomarker rods that were incorrectly or inaccurately positioned.
How to Add Rod Markers
① ③ ②Figure 24
Step
1. Select the desired slice in the catalog overview ① and click Add Rod ②.
2. Click in the magnified view ③ to finely adjust the marker position as needed.
3. Continue in this way until the required amount of rod markers have been added.NOTE: The Add Rod function is deactivated when a sufficient number of markers hasbeen added.
How to Repeat Image Slice Localization
Step
1. After you have manually modified rod markers, click Localize.
