What to Expect During Pre-Treatment
On the day of your procedure, the Gamma Knife nurse will accompany you
to the nearby Gamma Knife suite. An intravenous line will be started and
a local anesthetic injected to prepare for fitting the Gamma Knife head frame.
Fitting the head frame
To ensure effective planning and pinpoint accuracy of the Gama Knife radiation
treatment, you will be fitted with a lightweight head frame that will
remain in place for the entire procedure. The frame keeps your head stable
Taking an image of the treatment area
With the head frame in place, you will go next door to the Outpatient Imaging
Department for an MRI, CT scan and/or angiography (depending on your diagnosis).
These images are used to plan and map your individual treatment dosage.
Although you may have had these imaging procedures before, they need to
be repeated with the head frame on to define the location, size and shape
of the treatment area as precisely as possible.
Planning the procedure
With information from the new images, the treatment team uses sophisticated
computers to create a three-dimensional image map of your brain and an
individualized plan in preparation for your Gamma Knife treatment. Your
family is welcome to wait with you, and you are free to read, listen to
music, watch one of the big screen TVs or pass the time with any other
item you have brought, if you like.
