Tomotherapy is an advanced form of radiotherapy used to treat cancer patients. The term tomotherapy derives from the combination of two words, "tomos" meaning slice or section, and therapy. Synonyms for tomotherapy include Intensity Modulated Radiation Therapy (IMRT), Volumetric Modulated Arc Therapy (VMAT), and Stereotactic Body Radiation Therapy (SBRT). IMRT is a radiotherapy technique that utilizes high-intensity radiation beams to target specific regions of cancer cells while minimizing exposure to healthy tissue. VMAT is an advanced form of radiotherapy that delivers intensity-modulated radiation therapy using a rotating gantry. SBRT uses high doses of radiation to target small tumors in the body with high precision. Overall, these synonyms for tomotherapy are essential and necessary in the fight against cancer.
