Virtual reality (VR) enables realistic 3-D reconstructions for neurosurgical planning, improving surgeons' understanding of complex anatomy. Preoperative VR experience aids surgical procedures, though user-model interaction requires further enhancement.

Area of Science:

  • Medical Informatics
  • Virtual Reality Technology
  • Neurosurgery

Background:

  • Medical applications of virtual reality (VR) have evolved significantly, becoming crucial in medical informatics.
  • Advanced technologies allow for realistic 3-D reconstructions of anatomical structures and pathologies from large datasets.
  • VR systems with feedback enhance user interaction within virtual environments.

Purpose of the Study:

  • To describe the use of VR for advanced 3-D planning in neurosurgery.
  • To analyze different medical image volume rendering systems for 3-D neurosurgical planning.
  • To evaluate the impact of preoperative VR planning on surgical understanding and execution.

Main Methods:

  • Utilized commercial (Dextroscope) and open-source (3-D Slicer, FSL, FreesSurfer) volume rendering systems.
