Pronunciation[edit | edit source]
(toh-mah-THAYR-uh-pee)
How does tomotherapy work?[edit | edit source]
- Tomotherapy is a type of therapy in which radiation is aimed at a tumor from many different directions.
- The patient lays on a table and is moved through a donut-shaped machine.
Spiral pattern radiation[edit | edit source]
The radiation source in the machine rotates around the patient in a spiral pattern.
Imaging before therapy[edit | edit source]
- Before radiation, a 3-dimensional (3-D) image of the tumor is taken.
- This helps treating providers find the highest dose of radiation that can be used to kill tumor cells while causing less damage to nearby tissue.
