{{documentation/{{documentation/version}}/module-section|Module Description}}<br />
{{documentation/modulename}} allows users to display lines on Slicer. The main purpose of this module is to visualize needle trajectories as well as targets and cross-section along the needle path.<br />
Visualization is available on 3D view, and projections of lines and targets in 2D viewers. Each trajectory have independent properties, such as turn on/off visibility of the path/target, virtual offset, and control projection properties.<br />
Trajectories could also be modified in real time. This option allow the user to check intraoperatively for example, is this new path is safe before inserting needle.<br />
{{documentation/modulename}} does NOT allow creation of new trajectories. It only allows visualization of already existing rulers. However, PathPlanner module allows users to create new trajectories. <br />
<!--<br />
Here comes a description what the module is good for. Explain briefly how it works and point to the [[documentation/{{documentation/version}}/Modules/{{documentation/modulename}}#References|references]] giving more details on the algorithm.<br />
<br />
If you are documenting a CLI, the description should be extracted from the corresponding XML description. This could be done automatically using the following wiki template:<pre>{{documentation/{{documentation/version}}/module-description}}<br />

{{documentation/{{documentation/version}}/module-section|Use Cases}}<br />
{{documentation/modulename}} could be used for needle insertion like biopsies, but also for planning intervention, to find the optimal path to reach a target. By allowing reslicing along the trajectory path, it is possible to check if trajectory cross vital area or organs.<br />
With intraoperative images, it is also possible to overlay image and trajectory in order to verify current path is following planned path. By modifying in real-time the path, it is also possible to explore new path during surgery.<br />

As shown on the screenshot, there is two main parts in the GUI:<br />
* The display part<br />
* The advanced part (collapsed by default)<br />
Here is a description of items:<br />
# Delete and clear buttons are used to remove one (the selected line) or everything from the list<br />
# The list of trajectories with their path and target. Select a line to display their projection properties in items 5 and 6. Check/Uncheck elements to show/hide them.<br />
# When a line is selected, a virtual tip could be set by using the slider to change the length of the virtual offset.<br />
# This item allow the users to choose which list of ruler nodes will be used to populate the list (item 2)<br />
# This group of widgets contains line projection properties of selected trajectory (on item 2), which are:<br />
#* Color (change color of the line)<br />
#* Colored when parallel to plane (e.g. colored in green if parallel to green plane)<br />
#* Thicker on top of plane ( the part of the line on top of the plane is displayed thicker than the part under. Both thickness could be adjusted)<br />
#* Dashed or plain line<br />
# This group of widgets contains fiducial projection properties of selected trajectory (on item 2), which are:<br />
#* Color (if not using option below)<br />
#* Use fiducial color (use the same color for the projection than the fiducial)<br />
#* Outlined behing slice plane (different representation if the fiducial is in front or below slice plane)<br />
