The ViewRay™ system supports advanced radiotherapy techniques such as image-guided radiotherapy (IGRT) and stereotactic radiotherapy and radiosurgery (SRT and SRS), as well as 3D conformal and intensity-modulated radiation therapy (IMRT). With its MRI capabilities, the system is intended to provide stereotactic radiosurgery and precision radiotherapy for lesions, tumors, and conditions anywhere in the body where radiation treatment is indicated.
ViewRay’s design specifically enables the treatment of organs that are likely to move significantly during therapy, as lung tumors move when patients breathe. The ability to see soft tissue and adjust to its motion in real time can help assure clinicians that they are delivering the intended dose of radiation and avoiding normal tissues and critical structures, such as the spinal cord. Along with lung cancer, ViewRay technology may be beneficial in head and neck, prostate, breast, bladder, and other types of cancer where tumor and organ motion can affect treatments.
MRI guidance and intelligent software deliver advantages throughout the treatment process:
By capturing imaging and motion data throughout the radiotherapy process, the ViewRay system supports more targeted therapy for each patient. Physicians can continually adapt plans for improved accuracy and effectiveness—treatment by treatment and over the course of therapy—as the patient loses weight, the tumor changes shape, or the patient’s anatomy shifts.
