SIMULTANEOUS IMAGING AND TREATMENT Visibly Different because organ motion matters It is a simple truth. Involuntary life-sustaining movements don’t stop while your patients are receiving radiation therapy. As your patient moves —the tumor moves too! At ViewRay® we understand that the best way to deliver an accurate dose of radiation to a moving target is to be able to see inside the body at the time of treatment. That is why we designed the world’s first and only MRI-Guided Radiation Therapy System that can image and treat cancer patients simultaneously. MRIdian® is the next-generation...

APBI LEFT BREAST Female: 56 years old with T1bN0 Grade 1 adenocarcinoma and history of stage IV adenosarcoma of the uterus. Treated with accelerated partial breast irradiation (APBI) using LINAC based 3DCRT created with Pinnacle. RX: 0.5Gy in 10 fractions, 3.85Gy/Fx, over 2 weeks Structure Prescription Goals Linac Plan MRIdian Plan CONCLUSION Breast position and shape can differ daily and can be difficult to set up consistently; while heart dose is a limiting factor in left breast treatments. With MRIdian, you can deliver a highly conformal dose to the target with minimized dose to the...

MRIdian® Treatment Flow DAILY TREATMENT FLOW MRI Positioning Scan — Patient Setup An integrated MRI unit captures volumetric soft-tissue images for accurate pretreatment positioning in just a few seconds. The highquality soft-tissue contrast allows you to locate the tumor and align the patient to the treatment beams accurately without using X-ray, CT or surrogate registration markers. MRIdian allows for accurate automatic patient alignment. Auto-Contour MRIdian provides real-time imaging that clearly defines the targeted tumor from the surrounding soft tissue and other critical organs....

Track Tissue and Verify Target Track Tissue and Manage Patient Motion MRIdian® captures multiple soft-tissue imaging planes concurrently during treatment, refreshing the image multiple times per second. This real-time imaging allows you to track the movement of the tumor and the surrounding healthy tissue directly as well as verify the target and tracking boundary. If a tumor or critical organ moves beyond a physician-defined boundary, the treatment beam automatically pauses. When the tumor moves back into the predefined boundary, treatment automatically resumes. Beam control is especially...

CLINICAL FILES patient case studies ESOPHAGUS Adenocarcinoma of Distal Esophagus Mr. B. was treated for adenocarcinoma of the distal esophagus, with EUS demonstrating malignant appearing lymph nodes in the lower paraesophageal, paracardial, and celiac region. RX: 2.0Gy in 25 fractions; 50.0Gy total BREAST RECURRENCE Mediastinum Metastatic Adenocarcinoma Mrs. M. received prior treatment to her right breast with a conventional arrangement that included tangents and a superclav field (SCV). A recurrence in the perioartic arch node was close to the original target and required careful treatment...

Intra-abdominal Mesenteric Desmoid Tumor Ms. N. received treatment for a mesenteric desmoid tumor that did not respond to systemic therapy and was un-resectable. Several plans were made for this tumor due to its ability to move drastically both longitudinally and laterally. Ultimately her physician chose MRIdian® to treat her because of the system’s ability to accurately align and track motion. Image Top Left is the CT simulation with the PTV displayed. MRIdian images below taken during first fraction of treatment show the extreme displacement of the tumor. RX: 1.8Gy in 30 fractions; 54.0Gy...
