Investor FAQ

Why develop MRIdian® linac?

  • ViewRay’s Cobalt-based radiation technology is a breakthrough that integrates high quality intensity modulated radiation therapy (IMRT) with simultaneous magnetic resonance imaging (MRI) of soft tissues to provide optimal alignment, adaptation, and tracking.  However, Linear Accelerator (linac) systems are perceived to have several advantages.
  • Linear Accelerator technology obviates the need for the inspection, replacement, and disposal of Cobalt-60, and oversight from the Nuclear Regulatory Commission (or national agency in foreign countries).  Additionally, Linear Accelerators are [more] familiar to the market.
  • Linac-based radiation therapy delivery systems allow for higher dose, faster electronic variation of dose and electronic beam activation and deactivation.

How did ViewRay overcome the challenges of incorporating a linac in a compact MRI-guided system like the MRIdian?

  • ViewRay solved two major long-standing problems to compactly integrate a linac beam with an MRI system: 1) linac radiofrequency interference with the operation of the MRI and 2) MRI magnetic interference with the operation of the linac.
  • Linacs utilize high-powered microwave generators similar to equipment used in radar at airports.  These “radar stations” inside the linac create noise that can corrupt the delicate signals measured from the patient’s body to generate MR images.  ViewRay solved this problem by introducing technology similar to that used in stealth aircraft.  Stealth aircraft can hide from radar by using a coating that reflects and absorbs microwaves, thus preventing radar beams that strike the aircraft from bouncing back to the radar station.  In a similar manner, we reflect and absorb the output of the linac “radar station” to hide it from the MRI, producing images as noise-free as MRI images with no integrated linac.
  • MRIs utilize high-powered superconducting magnets that are required to image the patient’s tissues.  Many linac components will not operate properly when placed close to or inside these strong magnetic fields, and such placement is necessary to produce a compact system like the MRIdian linac.  ViewRay overcame this challenge by creating magnetic shielding shells that create voids in the magnetic field without significantly disturbing the magnetic field used for imaging.  This allows the linac to operate on the MRIdian gantry as if there were no magnetic field present.

Does the MRIdian linac technology limit or change any of the MRIdian features?

No, the MRIdian linac technology only improves our solution and is being developed to be an upgrade to existing MRIdian systems. ViewRay has applied the same double-focused multi-leaf collimator technology, originally designed to improve Cobalt-60 systems, to ViewRay’s MRIdian linac technology. We believe incorporating this beam shaping technology with the already sharp linac radiation source results in the sharpest linac beam to be developed in the industry.

What is the regulatory status of MRIdian® globally?

MRIdian with linac radiation is available for sale and delivery in the USA and EU. It is also approved in Canada, Japan, Korea, Taiwan, United Arab Emirates, and Turkey.

MRIdian with cobalt radiation is available for sale and delivery in: USA, EU, Japan, China, Taiwan, United Arab Emirates, and Korea.

Environmental Goals

2021-2023 GOALS

  • Reduce absolute emissions by 10%
  • Reduce water consumption by 5%

ViewRay has set a five-year goal of reducing CO2 emissions by 10 percent compared with the benchmark year of 2020. This goal is based on the climate goal of the United Nations to reduce global warming to significantly below 2 degrees Celsius. According to scientific studies, it will be necessary to cut back net emissions of global greenhouse gases to zero by 2060. This calculates to a reduction of 2.2 percent per year on average from 2015 onward. ViewRay is committed to this goal and would like to make an appropriate contribution.
