CLEVELAND, Feb. 4, 2021 /PRNewswire/ -- ViewRay, Inc. (Nasdaq: VRAY) announced today that Edogawa Hospital in Tokyo is the first hospital in Japan to treat patients with the MRIdian Linac System. Edogawa Hospital began treating patients in 2018 on the MRIdian cobalt system. The upgrade to MRIdian Linac combines MRI-guidance with a linear accelerator for faster and more accurate delivery of radiation therapy. 

"I am very pleased that Edogawa Hospital has the first MRIdian Linac in Japan. With this system, we can shorten the treatment time not only for our focused treatment areas such as pancreatic and lung cancers, but we can also treat patients with a wider range of cancers," said Dr. Yukihiro Hama, Head of the Department of Radiation Oncology at Edogawa Hospital.  "In addition to local Japanese patients, we have been actively treating foreign patients and believe that MRIdian Linac will enable us to contribute to society more effectively by improving patients' quality of life."

Unlike conventional radiation therapy systems, MRIdian combines MR imaging and radiation therapy in one system. This combination allows physicians to define treatment margins based on MR images of patient anatomy in support of the delivery of safe and effective radiotherapy -- including stereotactic body radiation therapy (SBRT), which utilizes ablative, high-doses in five or fewer treatment sessions. MRIdian enables continuous tracking of the target and surrounding soft tissues without fiducial markers, adaptation of therapy in response to daily anatomical changes, and automatic pausing of the radiation (beam gating) if the target moves outside of the user-defined boundary. This allows for delivery of the prescribed dose to the target while sparing surrounding healthy tissue and critical structures, potentially minimizing toxicities typically associated with radiation therapy.

Previously, ViewRay announced that the company had received Shonin approval from the Japanese Ministry of Health, Labor and Welfare (MHLW) to market the MRIdian Linac System featuring a linear accelerator (Linac) for beam delivery. Its predecessor, the MRIdian cobalt system, was the first MRI-guided radiation therapy system to receive Shonin approval in Japan in August 2016. Subsequently two MRIdian cobalt systems were installed at Edogawa Hospital and the National Cancer Center Japan.

Currently, 41 MRIdian systems are installed at hospitals around the world where they are used to treat a wide variety of solid tumors and are the focus of numerous ongoing research efforts. MRIdian has been the subject of hundreds of peer-reviewed publications, scientific meeting abstracts, and presentations. More than 11,000 patients have been treated with MRIdian.
