What accuracy is typical for dose delivery in Stereotactic Radiosurgery (SRS)?

In Stereotactic Radiosurgery (SRS), accuracy in dose delivery is crucial due to the precision required in targeting small lesions while minimizing exposure to surrounding healthy tissues. The typical accuracy for dose delivery in SRS is about 1%. This level of precision is achieved through advanced imaging techniques, sophisticated treatment planning systems, and highly focused radiation beams, which are all fundamental in ensuring that the prescribed radiation dose is accurately delivered to the targeted area.

While some considerations for radiation therapy may tolerate a larger range of accuracy, SRS necessitates tighter constraints to optimize treatment efficacy and safety. Therefore, an accuracy of approximately 1% is not only essential but also standard practice in ensuring the successful outcomes of SRS procedures, reinforcing the importance of precision in this specialized field of radiation therapy.
