Tumors can move even when you are lying still. Breathing can influence the position of tumors in your body especially in the lung or abdomen. In order to precisely treat a “moving target” we have an advanced technique called 4-dimensional (4D) imaging.

Using advanced planning technology, we can create a 3D movie loop showing the motion of your internal organs and the tumor while you breathe. Creation of this movie over time is called a 4D picture. By tracking your breathing, 4D planning allows your doctor to treat your cancer with radiation even when it moves so the treatment is right on target.
