The physician decides where the radiation beams will enter the body. The therapist will take x-rays and measurements of your body, and place marks on your skin. The marks are first made with a marker; they can be removed with soap. However, just prior to completing the simulation the therapist will make a few pinpoint marks on the skin that are permanent. These marks are made with a drop of ink and a pinprick, and are called tattoos. The therapists will refer to them daily during the course of your treatment. In addition, since radiation to a specific part of the body is often given only once during one's lifetime, the tattoos serve as a permanent record on your body. Once the simulation is complete, you will be given an appointment for your first treatment. This usually occurs 1-3 days later, provided you are medically ready to begin them. During this interval of time, the physicist and physician work to finalize the treatment plan. Also, custom designed blocks that will shield normal tissues are fashioned and mounted on trays that will be attached to the machine for use during your treatment. The therapist will instruct you on where you will go to change and receive your first treatment. |
