Before Treatment -
How to Prepare for Your Simulation
Follow the instructions provided by your health care provider. You may have a CT scan or PET scan before the session to map the exact spot of the cancer.
Please arrive 15 minutes early on the day of your appointment. It will give you adequate time to familiarize with the department and to change into a gown. You will then wait in one of our waiting areas until the radiation therapist arrives to escort you to the simulation suite.
Treatment simulation session
Before your radiation therapy begins, your treatment team carefully plans the details with a treatment simulation session. This is a meeting with you, your radiation oncologist and other members of the radiation team. Usually, your treatment planning will involve taking detailed images of your body and making precise marks in the areas that will receive the radiation beams. The team will also plan your body position on the table so that only a minimal amount of healthy tissue will be in the path of the radiation. This process will help you feel comfortable and give you an opportunity to ask any questions about your radiation treatment.
Positioning
First, the team will determine how you will be positioned on the table to optimize your treatment. It is important to find a comfortable position that you can hold for 15 - 30 minutes. You will have to be able to lie still. If the position is uncomfortable of awkward, an immobilizing device may used to hold you in place and give extra support. Measurements may be taken of prominent bones to be used as reference points.

To ensure that you will remain in position the entire treatment, an immobilizer may be created to prevent any movement during your therapy. If you are receiving radiation to your brain, head or neck, a mask may be made from firm plastic and molded to your face. This is a quick and painless process. During your treatment, the mask will be secured to the table and will gently hold your head in place. For body treatments, a Vac-Loc bag (a medical body beanbag) will be molded to hold and cradle your body in optimal position.
The purpose of these devices is to make you feel as comfortable as possible during the 15 - 30 minutes of your treatment. It is also extremely important to hold your position, without movement, to minimize the amount of healthy tissue within the radiation beam path.
Marking
A radiation therapist may mark your body to indicate the precise spot for your treatment. The type of markings used will depend on your tumor and the type of treatment that you will receive. Some marks can be made by a marking pen and are not permanent. Others marks are permanent tattoos, the size of a freckle, that cannot be rubbed off or washed away during the course of your treatment. Please discuss any concerns about receiving these tattoos with your radiation therapy team.
Treatment planning
Once you have finished the preliminary set-up for your treatment, your part of the treatment planning process is finished. Be sure that you ask your treatment team all the questions that you have, including:
- How long will each treatment last?
- How often will I have to have treatment?
- How many weeks will I have to have therapy?
- Can I drive myself home?
- What should I expect if I'm having chemotherapy and radiation at the same time?
- What side effects could I have? When do they start?
- How long will it take before we see the results of the radiation?
In the next few days, a medical physicist, or dosimeters, will work with the radiation oncologist to find the best way to direct the radiation at your cancer using state-of-the-art computers.
After simulation
After your simulation, you will be given an appointment card with the time and date of your first appointment for treatment. Your appointment time will usually be the same throughout your course of treatment (examples: Daily at 2:15 pm or daily at 10:45 am). Routine treatments are scheduled from Monday through Friday on a daily basis between 8:00 am and 4:30 pm, except for holidays.
