Sound Imaging Inc. has unveiled its MR patient motion and movement detection system for reducing motion artifacts during MR scans.

Developed over four years, the patent pending SAMM MD (Safety and Movement Monitoring with Motion Detection) solution equips MR staff with a range of capabilities for increasing patient safety and satisfaction, enhancing image quality and providing greater efficiency in scans.

“We are in negotiations with the US Patent and Trademark Office on the patent,” Sound Imaging told HCB News. “Our attorney expects the patent will take three to nine more months.”

Composed of patent pending hardware and software that integrates with the MR scanner, SAMM MD provides added safety with its motion detection technology, which picks up on when enough musculoskeletal movement occurs to create a potential motion artifact. It then visually and audibly alerts technologists and patients and offers the option to pause exams, saving on costly re-scans and reducing patient risks.

The solution also alerts and records remotely the entrance of anyone into an MR room on a 24/7 basis, and can optionally record an MR patient during their entire scan from the moment they set foot in the room.

Designed with an MR-compatible HD video display, the technology enables MR technologists to actually view patients in real time, and fully integrates with MR patient work lists to allow patient videos to be time-stamped and searchable, thereby reducing the potential for future legal exposure. In addition, video recordings can be utilized to train technologists, minimizing claustrophobia and increasing patient safety.

The development of the system is based on issues experienced by MR staff at John Hopkins University and is further supported by a 2015 study conducted by a team of researchers led by Dr. Jalal B. Andre, director of neurological MR at Harborview Medical Center and an associate professor of radiology at the University of Washington.

Evaluating added costs of motion artifacts in a typical imaging center, researchers found that re-scans were required in nearly 20 percent of studied examinations, costing one center an additional $115,000 annually.

The company plans to add additional features to the solution and will release two more products currently in provisional patent stage to complement the capabilities offered by SAMM MD.

“Once these are finished, we are going to call all of these plus another product we currently have our "MRI COMFORT SUITE", it said.
