Adaptive hypofractionation on the Akesis Gemini 360 lets us do that safely by re-imaging and re-planning every day. Quick summaryHypofractionation is radiation therapy delivered in fewer, larger doses than conventional treatment. At 5D Cancer Services, adaptive hypofractionation on the Gemini 360 typically finishes a course in 5–15 sessions instead of the 20–45 sessions that older techniques required, with comparable or better outcomes for many cancers. - Conventional radiation: 20–45 daily sessions over 4–9 weeks - Adaptive hypofractionation: typically 5–15 sessions over 1–3 weeks - Higher dose per session is delivered with sub-millimeter targeting - Daily imaging + plan adaptation protects healthy tissue - Strong evidence base in prostate, breast, lung, liver, and bone metastases - Available in St. George, Utah on the only Akesis Gemini 360 in the stateLast reviewed: 2026-05-12 ## Why fewer sessions can be safer For decades, radiation was delivered in small daily doses over many weeks because the imaging could not confirm exactly where the tumor was each day. Modern image guidance and adaptive planning have changed that: when we can see the tumor in 3D every visit and re-optimize the plan around it, we can safely give a much larger dose each time. The total biological dose to the tumor is similar — or higher — but the patient finishes treatment in a fraction of the visits. ## Where hypofractionation has the strongest evidence Randomized trials and large registry studies support hypofractionation in early-stage prostate cancer (5–20 sessions), early breast cancer (5–15 sessions), early-stage non–small-cell lung cancer (3–8 sessions), liver and pancreatic tumors (5 sessions), and bone metastases (1–5 sessions). Your radiation oncologist will recommend a fractionation schedule based on the cancer type, location, your overall health, and your goals. ## What the patient experience looks like A typical hypofractionated visit at 5D Cancer Services takes 30–45 minutes door to door. Most of that time is spent on imaging and plan adaptation; the radiation beam itself is on for only a few minutes per session. There is no anesthesia, no IV, and no overnight stay. Because the course is short, side effects tend to be more compressed but also resolve faster. Most patients continue working and driving themselves to treatment throughout the course. ## Learn More [### Adaptive SBRT 5-session high-dose body radiation.
