To perform computer assisted surgery, a 3-dimensional model of the brain is created using various imaging technologies such as:

• Computerized tomography (CT)
• Magnetic resonance imaging (MRI)
• Intraoperative MRI
• Positron emission tomography (PET)

The created model allows the doctor to view the best approach for performing surgery and treating the patient’s condition.

During the procedure, a computer system guides the doctor to the area of the brain that needs treatment. This method may be performed with other procedures, like deep brain stimulation for epilepsy.

Computer assisted surgery may be utilized in cases of:

• Brain tumors
• Arteriovenous malformations and other brain vascular lesions
• Tremors
• Functional problems like Parkinson’s disease
