What is SBRT?
Stereotactic Body Radiation Therapy (SBRT) is an advanced radiation technique that delivers a much higher dose per session than conventional radiotherapy — usually completed in five or fewer visits instead of 20–45.
Because the dose per session is high, SBRT requires sub-millimeter targeting, daily imaging, and tight margins to spare healthy tissue. The Akesis Gemini 360 re-images and re-plans the treatment at every session so the dose continues to land exactly where it should, even as the body changes day to day.
Conditions commonly treated with SBRT
- Localized prostate cancer (5-fraction protocols)
- Early-stage non-small-cell lung cancer (medically inoperable)
- Hepatocellular carcinoma and liver metastases
- Borderline-resectable and locally-advanced pancreatic cancer
- Oligometastatic disease (1–5 metastatic sites)
- Spinal and bone metastases
- Adrenal and kidney tumors in select cases
What to expect
After consultation and a CT simulation, the radiation oncology team builds an SBRT plan tailored to your anatomy. Each treatment session takes about 30–60 minutes; the dose itself is delivered in only a few minutes. SBRT is painless and outpatient — most patients return to work or normal activity the same day.
How adaptive SBRT differs from conventional radiation
Conventional radiation typically locks in a single plan at the start of treatment and delivers it 20–45 times. Adaptive SBRT on the Gemini 360 re-images and re-plans before every session, so the high dose still lands precisely on target even after weight loss, bowel/bladder filling, or tumor shrinkage.
