THE HEAD FRAME

One of the key components of Leksell Gamma Knife - the tool that allows your doctor to precisely pinpoint your tumor or problem - is the special stereotactic head frame.

This lightweight frame, which is attached to your head with four small screws, ensures that the radiation beams are precisely targeted.

The frame also prevents your head from moving during the treatment procedure, which ensures that only the target area in your brain receives radiation.

             IMAGING

After your head frame is in place, a number of advanced imaging tests - such as an MRI or CT scan - will be required to precisely locate the size, shape and location of your tumor, lesion or abnormality.

If your physician is treating a blood vessel abnormality, an angiogram may also be required. As you may already know, an angiogram involves the injection of a dye into your bloodstream so that the imaging procedure clearly shows the blood vessels and arteries in the brain.

The coordinate markers on your head frame, which are part of the images taken, will help your physician develop an exact plan for your procedure

 TREATMENT PLANNING              Once your images have been taken, you can sleep, rest or relax while your physician develops your specialized treatment plan. First, your brain images are computerized. Then, using Leksell Gamma Knife 3-D planning software, a treatment protocol is planned.

No two treatment plans are alike; every Leksell Gamma Knife patient’s plan is specifically designed to address his or her specific medical condition.

Because Leksell Gamma Knife includes a set of unique helmets that have 201 holes for the precise delivery of radiation to your brain, your plan will consist of one or more treatments using these helmets.
