remain still and in the same position throughout the simulation. Immobilization equipment and devices also ensure that the subsequent radiation treatment is delivered only to the intended area. Depending on the area to be treated, immobilization equipment may include plastic mesh masks that fit over the face; molds of the upper body, arm, or leg; bite blocks; or chin supports. Some children need sedation or anesthesia to help them remain still during the simulation and daily treatments. (Sedation or anesthesia also helps to reduce fear or anxiety during the process.) The simulation process can last 1–2 hours. Step Three: Planning The radiation oncologist creates a treatment plan that will administer the maximum amount of radiation to the tumor while protecting normal surrounding tissues. Planning can take several days from the time of the simulation to the day your child returns for treatment verification (see the next section). During that time, the radiation oncology team is creating an individualized treatment plan based on your child’s disease and specific requirements. Step Four: Treatment Verification After the treatment plan has been created, your child will need to visit the radiation oncology department for treatment verification, also called simulation . During treatment verification, your child will be placed in the proper treatment position with any necessary immobilization equipment or devices. The machine that delivers the radiation beam, called a linear accelerator, will go through a final test to confirm the treatment plan is correct, and X rays will be taken to verify the treatment position. Treatment verification usually lasts less than an hour. When this process is complete, your child will be ready to begin radiation therapy.
n WHO ARE THE MEMBERS OF THE RADIATION ONCOLOGY TEAM? Your child’s radiation treatment is planned, administered, and monitored by a multidisciplinary team of healthcare providers. Radiation Oncologist Radiation oncologists are doctors who have completed an additional 4 years of training in radiation oncology and 1 year of
medical or surgical internship after medical school. Radiation oncologists have specialized training and knowledge related to the planning and delivery of all forms of radiation therapy. Most are certified by the American Board of Radiology. Make certain your doctor is board-certified in radiation oncology. Nurse Practitioner Nurse practitioners are registered nurses who have completed advanced education in nursing and are certified and licensed to practice as nurse practitioners in their state of employment. The nurse practitioner has additional training in radiation oncology and is able to help you and your child manage the side effects of radiation therapy.
