• These images are used to plan the radiation treatments by helping the Radiation Oncologist locate the tumor and the critical structures. 

• A reference point is needed to align patients for treatment each day.
• A tiny amount of permanent ink is placed under the surface of the skin called a “tattoo”.

• Pen markings are also covered with a clear tape to help keep the marks from washing away during bathing.

   

These markings are aligned with the red positioning lasers, by the therapists.

• If radiation treatment is to be directed to the head and neck area, a mask will be made.
• If radiation treatment is required to the upper body, a pillow may be required which is designed to support the shoulders and arms.
