Summary
Image-guided surgery, or frameless stereotaxy, enhances surgical precision by integrating real-time instrument location with preoperative imaging. This technology minimizes invasiveness and improves lesion removal.
Area of Science:
- Neurosurgery
- Medical Technology
- Surgical Navigation
Background:
- Modern neurosurgical practice increasingly features image-guided surgery systems.
- Frameless stereotactic systems offer surgeons navigational data, correlating instrument position with preoperative imaging.
- These systems are crucial for minimizing invasiveness and improving surgical outcomes.
Purpose of the Study:
- To review the evolution of image-guided surgery from frame-based stereotaxy to current frameless systems.
- To present prevalent techniques and systems in surgical navigation.
- To discuss specific applications and future directions of frameless stereotaxy.
Main Methods:
- Review of literature on stereotactic principles and surgical navigation systems.
- Analysis of the development trajectory from frame-based to frameless stereotaxy.
- Examination of current technologies and their clinical applications.
Main Results:
- Frameless stereotactic systems are now widely advertised in neurosurgical journals.
- These systems enable accurate trajectory selection, precise identification of structures, and guided lesion removal.
- The core principle involves co-registration of the patient with imaging studies.
Conclusions:
- Image-guided surgery has evolved significantly, becoming a standard surgical navigation methodology.
- Frameless stereotaxy offers substantial benefits in minimizing invasiveness and enhancing surgical precision.
- Continued advancements are expected in the field of frameless stereotaxy.
