Curved-surface projection (CSP) visualizes functional MR imaging data, showing the brain's gyral and sulcal patterns. This technique is valuable for neurosurgery, preserving spatial relationships between brain structures and lesions.

Area of Science:

  • Neuroimaging
  • Medical Visualization
  • Functional Magnetic Resonance Imaging (fMRI)

Background:

  • Functional MR imaging (fMRI) data visualization is crucial for understanding brain function.
  • Existing visualization techniques may not optimally preserve spatial relationships between brain structures and pathologies.

Purpose of the Study:

  • To introduce and evaluate Curved-surface projection (CSP) as a novel technique for fMRI data visualization.
  • To demonstrate CSP's utility in identifying brain anatomy and its functional relevance, particularly in neurosurgical contexts.

Main Methods:

  • Development of the Curved-surface projection (CSP) technique for fMRI data.
  • Application of CSP to visualize the gyral and sulcal patterns of the brain.
  • Comparison of CSP with existing visualization methods regarding spatial relation preservation.

Main Results:

  • CSP effectively demonstrates the entire gyral and sulcal pattern of the brain simultaneously.
  • CSP preserves the spatial relationships between eloquent brain areas and lesions.
  • CSP aids in functional-to-anatomical mapping for neurosurgical patients with space-occupying lesions.

Conclusions:

  • Curved-surface projection (CSP) offers a valuable new method for visualizing fMRI data.
  • CSP enhances the understanding of brain anatomy and function, especially in complex neurosurgical cases.
  • The technique's ability to maintain spatial context is a significant advantage for clinical applications.
