ViewRay Incorporated is a medical device company. The Company is engaged in the design, manufacture and marketing of MRIdian. MRIdian is magnetic resonance imaging (MRI)-guided radiation therapy system that images and treats cancer patients simultaneously. MRIdian integrates MRI technology, radiation delivery and the Company's software and provides continuous soft-tissue imaging to locate, target and track the position and shape of soft-tissue tumors while radiation is delivered. MRIdian has four components, including MRI System, the radiation delivery system, integrated treatment planning and delivery software, and a safety and control system. It markets MRIdian to a range of customers across the globe, including university research and teaching hospitals, community hospitals, private practices, government institutions and freestanding cancer centers.

MRIdian is a next-generation, MRI-guided radiation therapy system that is comprised of four major components, (i) the MRI system, (ii) the radiation delivery system, (iii) integrated treatment planning and delivery software and (iv) a safety and control system.




MRI System

The MRI system is the component of MRIdian that captures soft tissue images of the patient’s body. To address the technical complications that arise from combining an MRI with a linac, we have designed a proprietary split superconducting magnet that allows treatment through a central gap, eliminating MRI components in the path of the beam. Our MRI system captures and displays live, high-quality images in three planes at two frames per second or in one plane at four frames per second. The images are used to track tissues and control radiation treatment beam delivery.

While other MRI systems in development utilize a high field strength magnet to provide a clearer image, use of higher field strength magnets results in distortions of soft tissue images by up to approximately six millimeters at 1.5 tesla and unfavorable dose distribution distortions, which are unacceptable for delivering accurate radiation therapy. We have engineered our MRI system to be able to produce clear images using a low field strength 0.35 tesla magnet which enables us to avoid the image and dose distortions that are a result of using a higher field strength magnet. In addition, MRIdian’s 0.35 tesla field strength prevents heating of the patient during uninterrupted imaging, which could occur in a higher field strength magnet requiring the imaging to be discontinued or interrupted.

Radiation Delivery System

Radiation is delivered from three Cobalt-60 radiation therapy heads symmetrically mounted on a rotating ring gantry, providing full 360 degree coverage and simultaneous dose delivery, as opposed to prior Cobalt-60 systems that have historically been limited by imprecise radiation dose applications. Each head is equipped with a double focused multi-leaf collimator, designed to overcome the wide-beam edge of previous-generation Cobalt-60 systems and shape the beam for precision radiation therapy treatments. It allows the delivery of treatment plans for 3D-CRT, IMRT and SBRT that are clinically equivalent to those produced on the most advanced linear accelerators available today. Stereotactic procedures are possible with a positioning accuracy of less than one millimeter. Cobalt-60 is used because it does not create any radio frequency which interferes with the MRI.

Integrated Treatment Planning and Delivery Software

Our treatment planning and delivery software can create treatment plans and manage the treatment delivery process. It is designed to create optimized 3D-CRT, IMRT and SBRT plans for delivery on MRIdian.
