>> To prepare for radiation treatment, you'll first go through a process called simulation, which lasts about 30 to 90 minutes.  During your radiation treatment, it is extremely important that you be in the same position every time.  To do this, a flexible mesh material will be molded over your head, neck and shoulders and attached to the table.  It hardens to form a mask.  Once the mask is dry, you'll have a CT scan or a PET scan of your head and neck area to help the team plan your radiation treatment.  After the scan, the radiation therapist will draw marks on your body.  These marks help us position you correctly on the table for each treatment.  Please do not wash off these marks. 

When you're done with simulation, you're doctor will outline the areas on the CAT scan that will be treated with radiation.  One to two days after you complete simulation, your doctor will review your case with a team of head and neck radiation doctors.  At this appointment, the doctors will discuss your case, examine you, and make any needed adjustments to your simulation CAT scan films.  Then, a medical dosimetrist will complete a computerized treatment plan using the simulation CT scans outlined by your doctor.  These plans are designed to spare as much normal tissue as possible, take about three to five days to complete, and are approved by your doctor before treatment begins.
