Radiosurgery is a medical procedure that uses high-energy radiation to treat tumors and other medical conditions. Some synonyms that can describe the same process are stereotactic radiation therapy and gamma knife surgery. Stereotactic radiation therapy is a more precise and targeted form of radiation therapy, where the radiation beams are delivered to the exact location of the tumor with high accuracy. Gamma knife surgery, on the other hand, uses specialized equipment that delivers gamma rays to a specific spot, treating the tumor while minimizing damage to surrounding healthy tissue. These alternative terms for radiosurgery are commonly used in medical fields to describe the type of treatment that a patient may receive.
