Area of Science:

  • Medical Visualization
  • Surgical Planning
  • Computer-Aided Surgery

Background:

  • Surgeons rely on multiple data sources (volumetric, 2D, vector-valued) for decision-making.
  • Integrating diverse datasets into a single, effective view presents a significant challenge.

Purpose of the Study:

  • To present a novel visualization approach for integrating various surgical data sources.
  • To enable effective exploration and manipulation of multimodal imaging and simulation data.

Main Methods:

  • Developed a visualization system to display volumetric (CT, PET, MRI), 2D (endoscopic), and vector-valued (simulations) data.
  • Incorporated interaction methods including traditional interfaces and real-time gesture-based controls.
  • Demonstrated application using medialization laryngoplasty to combine imaging modalities.

Main Results:

  • The system successfully integrates and displays information from diverse sources in a coherent view.
  • Allows for exploration, manipulation, and analysis of combined 2D and 3D imaging modalities and simulations.
  • Gesture-based interactions provide real-time control for enhanced user experience.

Conclusions:

  • The proposed visualization approach effectively addresses the challenge of integrating multimodal surgical data.
  • Facilitates improved surgical planning and decision-making through a unified data presentation.
  • Demonstrates the potential of combined modalities and natural interaction in surgical settings.
