Summary
Image-guided surgery, or frameless stereotactic surgery, uses digitizing pointers and computer programs to reformat diagnostic scans. This allows neurosurgeons to precisely align the patient
Area of Science:
- Neurosurgery
- Medical Imaging
- Surgical Technology
Background:
- Traditional stereotactic surgery relies on rigid fixation frames.
- Advancements in digitizing technology and computer software have enabled new surgical approaches.
Purpose of the Study:
- To introduce and explain the concept of image-guided surgery (frameless stereotaxy).
- To describe the fundamental principles of how frameless stereotaxy integrates patient anatomy with preoperative imaging.
Main Methods:
- Digitizing pointers are linked to computer programs.
- These programs reformat diagnostic imaging studies (CT/MRI).
- The system creates a 3D representation of the patient's anatomy and the surgical space.
Main Results:
- Enables the transposition of the patient's physical 3D space into a digital 3D image space.
- Facilitates real-time visualization of surgical instruments in relation to patient anatomy on preoperative scans.
Conclusions:
- Frameless stereotaxy represents a significant advancement in neurosurgical navigation.
- This technology enhances precision by integrating preoperative imaging directly into the surgical workflow.
