IMRIS

IMRIS Inc. (Innovative Magnetic Resonance Imaging Systems) was a medical equipment company based in Minnetonka, Minnesota, United States. The company which was founded in Winnipeg, Manitoba, Canada, developed and marketed intraoperative image-guided therapy environments for use during surgical or interventional procedures. The system – sold as VISIUS Surgical Theatre – integrated magnetic resonance imaging (MRI), computed tomography (CT), X-ray angiography and fluoroscopy into the operating room. The company evolved from research conducted through Canada’s National Research Council.

The IMRIS intraoperative MRI and CT products were mounted on ceiling rails that brought the image modality (scanner) to the patient rather than having to transport or reposition the patient. The VISIUS iMRI and iCT products were available in multiple room configurations so imaging could be utilized in other rooms for intraoperative or diagnostic scanning.

In 2011, the company announced it was developing an MRI-compatible image-guided surgical robot specifically designed for minimally-invasive neurosurgery. In November 2012, the company announced that it was moving its headquarters to the Minneapolis area. They completed their move in July 2013.

In late May 2015, news broke that IMRIS had "filed for chapter 11 bankruptcy protection with a buyout offer of $9.5 million from secured lender Deerfield Management Co. LP." due to problems competing with larger health care businesses. Chapter 11 proceedings were finalized on August 19, 2015, with Deerfield Imaging agreeing to acquire most of IMRIS' assets.
