This study adapted 3D-navigation for interstitial brachytherapy, achieving high accuracy in phantom and specimen tests. This innovative technique enhances treatment planning and virtual simulation for improved patient outcomes.

Area of Science:

  • Medical Physics
  • Radiation Oncology
  • Surgical Navigation

Context:

  • Interstitial brachytherapy requires precise applicator placement for optimal dose delivery.
  • Current 3D-navigation systems need adaptation for interstitial brachytherapy needle guidance.
  • Virtual simulation capabilities can improve safety by identifying critical structures.

Purpose:

  • To adapt and evaluate a 3D-navigation system for interstitial brachytherapy.
  • To assess the accuracy of needle placement using free and template-guided navigation.
  • To validate the system's potential for clinical application through phantom and anatomical specimen testing.

Summary:

  • The EasyGuide Neuro navigation system was modified to integrate interstitial brachytherapy needles.

  • Positioning accuracy was tested on phantoms, with 91% of attempts within 5 mm and 94% within 4 mm on a rigid table.
  • Both free and template-guided navigation methods demonstrated comparable accuracy, with mask systems ensuring stable positioning.

    • Impact:

    • Demonstrates the feasibility and accuracy of 3D-navigation for interstitial brachytherapy.
    • Suggests potential for improved treatment planning, dose distribution, and patient safety.
    • Highlights the importance of rigid tables and patient support systems for clinical success.
