Profile: ViewRay Inc (VRAY.A)
19 Jul 2019
ViewRay, Inc., incorporated on October 6, 2013, through its subsidiary ViewRay Technologies, Inc., designs, manufactures and markets MRIdian, the magnetic resonance imaging (MRI)-guided radiation therapy system to image and treat cancer patients simultaneously. The Company offers radiation therapy technology combined with magnetic resonance imaging. MRIdian integrates MRI technology, radiation delivery and the Company's software to locate, target and track the position and shape of soft-tissue tumors while radiation is delivered.
MRIdian delivers radiation to the tumor accurately while delivering less radiation to healthy tissue. MRIdian provides real-time imaging that defines the targeted tumor from the surrounding soft tissue and other critical organs during radiation treatment. MRIdian allows physicians to record the level of radiation exposure that the tumor has received and adapt the prescription between fractions as needed. MRIdian provides improved tumor visibility and patient alignment; on-table adaptive planning; ability to track tumors and manage patient motion, and records and evaluates the delivered dose. The Company markets MRIdian through a direct sales force in the United States and distributors in the rest of the world.
MRIdian consists of approximately four components: the MRI system, the radiation delivery system, integrated treatment planning and delivery software, and a safety and control system. The MRI system is the component of MRIdian that captures soft tissue images of the patient's body. The Company has designed a split superconducting magnet that allows treatment through a central gap, eliminating MRI components in the path of the beam. The Company's MRI system captures and displays live images in approximately three planes at over two frames per second or in a plane at over four frames per second. The images are used to track tissues and control radiation treatment beam delivery. Radiation is delivered from approximately three Cobalt-60 radiation therapy heads symmetrically mounted on a rotating ring gantry, providing approximately 360-degree coverage and simultaneous dose delivery. The Company's treatment planning and delivery software can create treatment plans and manage the treatment delivery process. It is designed to create optimized three-dimensional conformal radiation therapy (3D-CRT), intensity modulated radiation therapy (IMRT) and stereotactic body radiation therapy (SBRT) plans for delivery on MRIdian. The software includes auto-contouring, dose prediction and treatment plan optimization. MRIdian also contains redundant computer control for safety and system logging, and double encoders on all axes of motion for safety.
The Company competes with Varian Medical Systems, Inc., Elekta AB and Accuray Incorporated.
