Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Computer-Assisted Surgery

Background:

  • Stereotactic neurosurgery, while established, faces accuracy issues with frame-based systems due to setting errors.
  • Frameless stereotactic neurosurgery using neuronavigation can cause surgeon discomfort and requires shifting focus from the surgical field.

Purpose of the Study:

  • To explore the application of augmented reality (AR) in stereotactic neurosurgery to address existing limitations.
  • To evaluate how AR can improve accuracy, safety, and surgeon ergonomics in stereotactic procedures.

Main Methods:

  • Review of studies applying AR in frame-based stereotaxy using tablet computers for error checking.
  • Analysis of research on frameless stereotaxy guided by head-mounted display-based AR for improved surgeon posture.
