ViewRay - A New Paradigm in Radiation Oncology

ViewRay MRIdian users now have eight years of Clinical Experience in MR-guided Radiation Therapy and more than 16000 patients have been treated with MRIdian®. Because of the diagnostic quality real-time MRI visualization, it allows a number of different treatment options: Stereotactic MR-guided Adaptive RadioTherapy SMART is the future of SBRT. MRIGRT, MRSRS, Real-time On-table Adaptive Radiotherapy  ROARs. ViewRay’s MR-Linac allows hypofractionation and dose escalation in moving targets. With 8 MR images per second during the whole treatment doctors dare to apply curative dosage. It is because they can see what they are treating and stop the beam when needed to spare healthy tissue. 8 FPS MRI cine during treatment is nice!

The ViewRay MRIdian® MR-Linac fits in a standard RT treatment vault / linac bunker.

MR-linac MRIdian Linac from ViewRay

The MRIdian® from ViewRay enables cancer specialists to deliver truly personalized and adaptive radiation therapy. It provides a unique combination of simultaneous radiation therapy and real-time magnetic resonance imaging (MRI) for the treatment of cancer.

Adaptive Workflow & Software

With MRIdian, physicians are able to directly view and track the tumor during treatment and adapt to changes in the tumor and surrounding tissue. Additionally, because it uses MRI technology instead of computed tomography (CT) scans, MRIdian is able to reduce the level of radiation exposure.

True image guided adaptive radiation therapy

The MRIdian® system gives clinicians a fresh and safe approach to observing, assessing, and personalizing a patient’s treatment. The MRIdian® system provides high-quality pretreatment images and continuous soft-tissue imaging during treatment while the beam is on.

The Software

With the MRIdian® system’s unique treatment planning and delivery software, physicians are able to define the parameters of the treatment process in their prescriptions. Welcome to see it in clinical use.

See the target

MRI is the clinically preferred method of imaging soft tissue. MRI technology can give clinicians a clearer view of the patient’s internal organs, such as the lung. It also enables on-line imaging with beam on, to see any movements in the target volume (TGV) or organs at risk (OAR).

Advanced treatments

Support for advanced and conventional radiation therapy techniques, including MRIGRT, SRS and SRT, IMRT, and 3D conformal therapy. Software tools that help physicians better manage the progress of personalized treatments.
