Key Investigators

  • Atsushi Yamada (Shiga University of Medical Science, Japan, ayamada@belle.shiga-med.ac.jp)
  • Junichi Tokuda (BWH)
  • Koichiro Murakami (BWH, Shiga University of Medical Science, Japan)

Project Description


  • The goals of the entire project are to display pathways to a target tumor avoiding anatomical structures including arteries and other organs and to use these pathways for planning.
  • The goal of this project is to implement the function to pick up geometrically specific pathways (short distance, small oblique and so on) from calculated pathway candidates.

Approach, Plan

  • Implement function to display maximum and minimum length paths
  • Implement function to display maximum and minimum oblique paths
  • Fix bugs


  • Created this page (1/6)
  • Private GitHub repository: Percutaneous Path Designer module
  • Implemented planning part (1/6)
  • Implemented needle path selection part (1/6)
  • [Planning procedure]
    • Set a target point, obstacles, region of insertion candidate
    • Obtain the path candidates with visualization as sun ray
    • Select one path from the path candidates by using the slider interface
    • Find a needle insertion point obtained by extending the tip of the selected needle path candidate
