This study introduces an advanced image analysis system for stereotactic neurosurgery, enabling simultaneous display of multi-modal brain images. The system enhances surgical precision by integrating various imaging techniques for improved visualization and navigation.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Computer-Aided Surgery

Background:

  • Stereotactic neurosurgery requires precise image guidance.
  • Integrating diverse imaging modalities (MRI, CT, DSA, PET) presents challenges.
  • Existing systems lack dynamic multi-image display and inter-modality information exchange.

Purpose of the Study:

  • To develop an integrated image analysis system for stereotactic neurosurgery.
  • To enable simultaneous visualization of multi-modal brain images in common coordinates.
  • To facilitate information interchange and spatial referencing across different imaging datasets.

Main Methods:

  • Development of a system based on a stereotactic frame and microcomputer.
  • Implementation of a dynamic multi-image environment for simultaneous display of MRI, CT, DSA, and PET.

  • Utilizing stereotactic frame fiducial markers for common coordinate registration and point/region transfer between images.

    • Main Results:

    • The system allows simultaneous display of multiple imaging modalities (MRI, CT, DSA, PET) in a dynamic environment.
    • Point registration and region of interest analysis are supported in three-dimensional space.
    • Phantom studies confirmed minor system distortions, indicating suitability for clinical application.

    Conclusions:

    • The developed image analysis system offers significant advantages for stereotactic neurosurgery.
    • It enhances surgical planning and execution through integrated multi-modal image display and analysis.
    • The system improves upon previous imaging procedures, facilitating more accurate and efficient interventions.
