Method and apparatus for displaying a field of a brain of a patient and navigation system for brain surgery

摘要

A method and an apparatus for displaying a part of a brain of a patient is provided. Laser-Doppler-images are acquired before and after a stimulation. The laser-Doppler-images comprise information about a blood motion or about a perfusion at the acquired part. Then, the blood motion images acquired before and after the stimulation are compared to identify areas in the brain of the patient which are related to the stimulation.
