What is brain SRS?
Stereotactic radiosurgery is not actually surgery — there is no incision. It is a highly focused radiation treatment that delivers an ablative dose to a small intracranial target in one (single-fraction SRS) to five (fractionated SRT) sessions.
The Akesis Gemini 360 uses thin-slice imaging and a custom thermoplastic mask to immobilize the head, then delivers each treatment with sub-millimeter precision while sparing healthy brain tissue around the target.
What SRS is used for
- Brain metastases (single, oligometastatic, or multiple lesions)
- Acoustic neuroma (vestibular schwannoma)
- Meningioma — including small or surgically inaccessible cases
- Pituitary adenoma
- Trigeminal neuralgia (select cases)
- Arteriovenous malformations (AVM) in collaboration with neurosurgery
What to expect on a treatment day
You'll be fitted into your custom mask, positioned on the treatment table, and imaged so the system can confirm sub-millimeter alignment. The radiation itself is silent and painless and takes only a few minutes; the full appointment is typically 45–60 minutes. Most patients drive themselves home and return to normal activity within 24 hours.
Coordination with your other doctors
Brain SRS decisions are made jointly with your neurosurgeon and medical oncologist. We share imaging and treatment summaries securely so your full care team stays aligned.
