Adaptive radiotherapy on the Akesis Gemini 360 treats breast cancer by combining onboard CBCT imaging with a treatment plan that can be adjusted at each visit, accounting for daily changes in breast position, swelling, or setup. This allows the radiation oncology team to target the treatment area precisely while working to limit dose to the heart, lungs, and surrounding tissue.
Why Does Breast Position Matter During Radiation Therapy?
Breast tissue shifts slightly from day to day due to patient positioning, breathing, and tissue changes over the course of treatment. A plan built from a single scan at the start of care may not reflect what the body looks like by week two or three. Adaptive radiotherapy addresses this by imaging the treatment area immediately before each session and adjusting the plan accordingly, rather than relying on one static plan for the full course. You can read more about this process on our adaptive radiotherapy overview.
How Does the Akesis Gemini 360 Support Breast Cancer Treatment?
The Akesis Gemini 360 is a linear accelerator with onboard CBCT imaging, which means the imaging system and the treatment system are built into the same unit. This is different from older setups where imaging and treatment happen on separate machines, introducing more room for positioning error between the two steps. For breast cancer cases, this integration supports techniques like dose painting, where different areas within the treatment field can receive different dose levels based on what the daily imaging shows. Details on how this imaging works are explained on our imaging page.
What Does a Breast Cancer Radiation Session Involve?
A typical session begins with the patient positioned on the treatment table, followed by a CBCT scan to capture the current anatomy. The care team reviews that scan and, if needed, adjusts the plan before treatment begins. This happens at every visit, not just the first one. Because the system is designed to work efficiently once imaging is reviewed, many patients describe the time on the table as manageable, though exact session length varies by case complexity and treatment area. For a broader walkthrough of what to expect from first visit to final session, see our patient journey page.
How Many Sessions Does Breast Cancer Treatment Typically Require?
The number of sessions depends on the stage of disease, the specific treatment area (whole breast, partial breast, or chest wall and nodal regions), and factors your radiation oncologist evaluates during planning. Session counts for breast cancer radiation can vary meaningfully between patients, and adaptive techniques are sometimes used to support shorter overall courses in appropriate cases. Your care team will outline a specific schedule only after reviewing your imaging and treatment goals, not before.
Is Adaptive Radiotherapy Appropriate for All Breast Cancer Diagnoses?
Not every case is the same, and the right approach depends on tumor location, prior treatment history, and overall health. Some patients may be candidates for more targeted approaches, while others require a broader treatment field. These decisions are made individually by the treating radiation oncologist based on diagnostic imaging and staging information specific to that patient. Our conditions page lists the full range of cancers and conditions treated at our centers, including breast cancer alongside prostate, gynecologic, lung, liver, pancreatic, and head and neck cancers.
What Should I Do Next If I'm Considering Radiation Therapy for Breast Cancer?
If you or a family member has been diagnosed with breast cancer and radiation therapy is part of the conversation, the next step is usually a consultation where your imaging and pathology are reviewed by a radiation oncologist. Our team can discuss whether adaptive radiotherapy on the Akesis Gemini 360 fits your specific situation, and insurance verification is handled as part of the intake process. You can reach our team through our contact page to ask questions or schedule a consultation.
Every breast cancer diagnosis is different, and treatment planning should always involve a conversation with your own physician about what approach may help in your specific case. Patients often report that daily imaging gives them more confidence in their treatment plan, though individual experiences and outcomes vary.
