Stereotaxic brain surgery. View of a surgeon during a stereotaxic brain operation. The surgeon is adjusting a frame which is screwed onto the patient's skull to provide support and guidance for the tools to be used in the operation. The patient's head has been scanned (by MRI or CT scanning) to determine the exact position of the target area. This reduces the chance of damaging healthy brain tissue. Surgery is conducted through a hole drilled into the skull. Stereotaxic brain surgery is performed in cases of a brain tumour, either to remove a biopsy sample for analysis or to remove the growth, and also to cure chronic pain or psychological disorders.
