First, thank you to @heavyphil, @jeffmarc, @vircet, and @bens1 for contributing information about the somewhat confusing availability (or lack thereof) of gated SBRT treatment centers. This is an example of the tangible benefits of this portal and the incredible knowledge of the men who participate in it. @bens1's comment about some treatment centers hiring former Viewray employees to maintain their existing systems and preserve their investment makes sense and would explain why some centers no longer use MRIdian, while others continue to do so.

Here is some additional information I found this morning:

"ViewRay Systems, Inc. (formerly known as ViewRay, Inc.) was a company that designed, manufactured, and marketed the MRIdian MRI-guided radiation therapy system. The company ceased operations and filed for Chapter 11 bankruptcy in October 2023, and its assets were acquired by Chindex Medical Limited (a subsidiary of Shanghai Fosun Pharmaceutical (Group) Co., Ltd.). " At least one site that had ceased MRIdian operation in 2023, the Siteman Cancer Institute at Washington University Medical Center in St. Louis, resumed delivering MRIdian treatment in February of this year.
