Summary
This study developed a 3D virtual liver model and a virtual hepatectomy system for surgical simulation. The system accurately mimics liver resection procedures, enhancing surgical training.
Area of Science:
- Medical imaging and simulation
- 3D reconstruction techniques
- Surgical planning and training
Context:
- Liver surgery requires precise anatomical understanding.
- Current simulation methods may lack detailed internal structure visualization.
- Developing realistic virtual surgical environments is crucial for training.
Purpose:
- To investigate the methodology for creating a virtual liver resection system.
- To develop a 3D visualized liver model from serial sectional images.
- To establish a virtual hepatectomy system for simulating surgical procedures.
Summary:
- A 3D virtual liver model was constructed using serial cross-section images obtained from perfused liver samples.
- The model was integrated into a virtual hepatectomy system utilizing freeform modeling and haptic feedback.
- The system allowed for virtual scalpel manipulation to perform simulated liver resections.
Impact:
- The developed 3D visualized liver and virtual hepatectomy system provide a realistic simulation environment.
- This technology can enhance surgical training by allowing practice of resection procedures.
- The simulation process demonstrated consistency with clinical practice, offering valuable insights for surgical planning.
