Module Description

PercutaneousPathDesigner is a Slicer4 module designed to display bundles of needle path candidates to avoid blood vessels, bones and specific anatomies and create the path from the bundle. The bundles of path candidates is calculated based on a target point, a skin model and an obstacle model. After the calculation, you can inspect the each path on the bundles comparing with the longest path and the shortest path. The location of the skin entry point of each path can be modified by extending and shrinking the path. The target point and the skin entry point you modified on the selected path could be output as a MarkupsFiducial List. You can clean up the models generated from this module.

Panels and their use

PercutaneousPathDesigner Parameters panel

• Parameters panel
  • Target Point requires MarkupsFiducial List created in Markups Module which has only one markup.
  • Output Fiducial List requires MarkupsFiducial List created in Markups Module which has no markups.
  • Skin Model requires a model which represents a skin, that is, a surface on the needle tips.
    • Opacity Slider can change the opacity parameter of the Skin Model selected.
  • Obstacle Model requires a model which represents obstacles needle paths should avoid.
    • Opacity Slider can change the opacity parameter for the Obstacle Model selected.
  • Path Analysis Start button starts creating path candidates from target point to the skin model to avoid the obstacle model.

PercutaneousPathDesigner Outcomes panel

• Outcomes panel
  • All Paths (Yellow) check button displays all path candidates shown as the yellow bundles of lines.
    • Opacity Slider can change the opacity parameter for the yellow bundles.
  • The Longest Path (Green) check button displays the longest path as the green line.
  • The Shortest Path (Blue) check button displays the shortest path as the blue line.
  • The Path Candidate (Red) check button displays the one of the yellow bundles as the red line.
    • Path Candidate (No.) Slider can select the line from the yellow bundles.
    • Point Candidate on the Path Slider can extend and shrink the selected red line from the skin entry point.
    • Point on the Path button writes the target and the tip position Markups to the Output Fiducial List you set in the Parameters panel.

PercutaneousPathDesigner Configurations panel

• Configurations panel
  • Delete Paths button erases the all models created by this module.
