The PercutaneousPathDesigner module is a Slicer4 module designed to visualize bundles of needle path candidates to avoid blood vessels, bones and specific anatomies and specify skin entry points on the path candidates. The bundles of path candidates and the skin entry point on each path in the bundles are calculated based on a target point, a skin model and an obstacle model. This bundle expression might help you grasp safety paths easily. It is also possible to evaluate the each path on the bundles based on the length and the trajectory comparing with the longest and the shortest paths. The location of the skin entry point on each path could be modified by extending and shrinking the path. The skin entry point on each path could be output as a MarkupFiducial List. After getting the outcomes, you can clean up the models and transform matrixes generated from this module.

Use Cases

The PercutaneousPathDesigner module is a useful tool for planning needle and probe paths. Percutaneous thermal ablations including radio frequency, microwave and cryotherapy require such probe trajectories to avoid blood vessels, bones and specific anatomies to reach the probes to target tumors. Needle biopsy also requires safety paths to gather multiple tissue. For these cases, this module can help to obtain the path candidates based on the target point, a segmented obstacle model to avoid and another segmented model which represents skin entry surface.
