Stereotactic Radiosurgery/Radiotherapy (SRS/SRT) is primarily used to treat small benign and malignant lesions and diseases within the skull. Through high-precision positioning steps and imaging navigation technology, it safely and accurately delivers single or multiple fraction high-dose radiation beams focused on the intracranial lesion area, achieving effects similar to surgery, making it a non-invasive treatment. SRS/SRT can be used to treat small brain metastases, slowly growing benign brain tumors (such as meningiomas, acoustic neuromas, and pituitary adenomas), or for head tumors that require re-radiotherapy. In addition, SRS/SRT can also be applied to treat certain non-tumor-related conditions, such as arteriovenous malformations and trigeminal neuralgia.
