Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Surgical Navigation

Background:

  • Traditional surgical visualization can be limited.
  • Frameless stereotactic techniques offer advanced spatial awareness.

Purpose of the Study:

  • To describe a simulated surgical setup using frameless stereotactic techniques.
  • To enable surgeons to visualize the surgical field overlaid with medical images.
  • To provide a true three-dimensional (3D) navigation system for enhanced surgical planning.

Main Methods:

  • Development of a simulated surgical setup.
  • Integration of frameless stereotactic techniques.
  • Overlay of segmented volumetric medical images onto the surgical microscope's field of view.
  • Tracking of surgical devices using stereo vision cameras.

Main Results:

  • Surgeons can visualize the surgical site and inner anatomy in 3D.
  • The system allows for "fly-through" exploration of the surgical area.
  • Real-time tracking of surgical devices determines their spatial relationship to the target lesion.

Conclusions:

  • The described system enhances surgical visualization and spatial understanding.
  • This 3D navigation system supports improved surgical approach selection.
  • The technology aids in precise localization of surgical devices relative to the target.
