Tomotherapy - (pronounced) (toh-mah-THAYR-uh-pee) form of therapy in which radiation is directed at a tumor from many different directions. The patient lies on a table and is moved by a donut-shaped machine. The radiation source in the device rotates in a spiral around the patient. Before the radiation, a three-dimensional (3-D) image of the tumor is made. This helps doctors find the highest dose of radiation that can be used to kill tumor cells while causing less damage to nearby tissue. Tomotherapy is a form of intensity-modulated radiation therapy (IMRT). Also called helical tomotherapy
