Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Software Development

Background:

  • Neurosurgical planning relies on defining critical areas and trajectories.
  • Multimodal medical imaging is increasingly used to support surgical planning.
  • Existing neuronavigation systems can benefit from integrated multi-informational data.

Purpose of the Study:

  • To present a novel software environment for comprehensive multimodal and multi-informational planning in neurosurgery.
  • To enable advanced neuronavigation capabilities for epilepsy and tumor surgeries.

Main Methods:

  • Developed a data fusion environment for neuronavigation, integrating registration, segmentation, and 3D visualization tools.
  • Fused multimodal data including MRI, MRA, MEG, and fMRI for surgical script definition.

Related Experiment Videos

  • Processed data through registration, segmentation, 3D display, and surface-based representation for neuronavigation software compatibility.

    • Main Results:

    • Demonstrated multimodal neuronavigation using two clinical cases.
    • Utilized lesional areas for surgical path definition and sulci/vessels for anatomical context.
    • Integrated MEG and fMRI data to precisely locate functional high-risk areas.

    Conclusions:

    • The developed software environment provides valuable preoperative multi-functional and anatomical data support for neurosurgical procedures.
    • Access to integrated multimodal data within the neuronavigation system enhances surgical planning and execution.
