Area of Science:

  • Thoracic surgery
  • Medical simulation
  • Pulmonary imaging

Background:

  • 3D computed tomography (CT) enables static surgical simulation in thoracic surgery.
  • A limitation of current 3D CT simulation is its inability to reflect intraoperative lung deformation.
  • Dynamic simulation for lung deformation has not been previously developed.

Purpose of the Study:

  • To develop a novel simulation system for generating dynamic images.
  • To create a system that utilizes patient-specific CT data for dynamic simulation.
  • To advance surgical simulation in pulmonary resection.

Main Methods:

  • Developed original software named Resection Process Map.
  • The software semi-automatically generates virtual dynamic images from patient-specific CT data.
  • Retrospectively evaluated accuracy in 18 cases by comparing virtual and actual surgical images.

Main Results:

  • Successfully generated virtual dynamic images for all 18 cases.
  • The Resection Process Map accurately delineated 98.6% of vessel branches and 100% of bronchi.
  • Median image generation time was 121.3 seconds.

Conclusions:

  • Successfully developed a novel dynamic simulation system.
  • The Resection Process Map is suitable for anatomic pulmonary resection.
  • This system represents a significant advancement in surgical simulation for lung procedures.
