A novel head fixation system with carbon fiber pins enables artifact-free intraoperative CT scans during neurosurgery. This system enhances surgical imaging accuracy for complex procedures.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Biomedical Engineering

Background:

  • Intraoperative imaging is crucial for guiding neurosurgical interventions.
  • Traditional head fixation methods can cause artifacts in computed tomographic (CT) scans.
  • Artifacts obscure critical anatomical details, potentially compromising surgical outcomes.

Purpose of the Study:

  • To develop and describe an advanced head fixation system for intraoperative CT scanning.
  • To evaluate the system's ability to provide artifact-free neurosurgical images.
  • To improve the quality of real-time imaging during open-field neurosurgery.

Main Methods:

  • A head fixation system was designed utilizing four carbon fiber head pins.
  • Modified pin supporting devices were engineered to ensure stability and minimize image interference.
