Introduction to Image-Guided Surgery
Since the mid-1970’s, image-guided surgery has emerged as an accepted and clinically appropriate alternative to traditional surgery.

Modern image-guided surgery has been described in the clinical literature using a variety of terms such as: “surgical navigation,” “computer assisted surgery,” “surgical stimulation,” “3-D computer surgery,” “surgical navigation”

Using surgical navigation methods, physicians may make more accurate diagnoses before and during surgery.

Advanced technologies provide computerized, three-dimensional
viewing so physicians and surgical
teams can precisely locate and position surgical instruments in the anatomic field and view the results on their visual displays

As a result, procedures are shorter and protocols are improved.

Surgical navigation may also be less invasive than traditional surgery as surgeons may be more accurate using technologically advanced devices in place of (or in addition to)
the traditional hand-guided, mechanical devices during surgery.

This allows for an increased level of patient safety and an overall reduction in patient morbidity.

In addition, recent enhancements to surgical navigation technology have enabled new and more minimally invasive procedures to be possible.
