For surgical procedures using neuronavigation, no special preparation beyond standard surgical readiness is required. However, before the surgery, detailed Magnetic Resonance (MR) or Computed Tomography (CT) images of the target area are obtained. These 3D images are loaded into the neuronavigation system to create a detailed map of the surgical field. After the patient is brought into the operating room, the surface anatomy of the surgical area is introduced to the computer system with the help of a probe. This integration allows the surgical team to determine the shortest and safest path to the area to be operated on. The neuronavigation device uses the patient's 3D radiological data to precisely indicate various risk areas in the brain or spinal cord. This enables the surgeon to focus solely on the problematic tissue, protecting surrounding healthy tissues, and performing the surgery more safely and effectively.
