Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Computer-Aided Surgery

Background:

  • Stereotactic neurosurgery requires precise localization of targets within the brain.
  • Integrating multi-modal imaging data is crucial for accurate surgical planning.
  • Existing systems may lack seamless integration and interactive planning capabilities.

Purpose of the Study:

  • To develop and present a prototype display workstation for stereotactic neurosurgery.
  • To demonstrate the integration of various imaging modalities for surgical planning.
  • To explore the utility of computer-assisted tools in defining safe surgical pathways.

Main Methods:

  • Development of a prototype display workstation.
  • Acquisition of patient image data using computed tomography (CT), magnetic resonance imaging (MRI), and digital subtraction angiography (DSA) with a stereotactic frame.
