Sound Imaging launched this month its new, patented MR patient motion and detection system for reducing motion artifacts.
Dubbed SAMM MD (Safety and Movement Monitoring with Motion Detection), the solution is designed to reduce repeat scans due to movement and prevent interruptions to workflow, while ensuring patients are comfortable and safe.
“Patient movement, whether voluntary or involuntary, creates a motion artifact. These images appear blurred, streaked, or shaded and may interfere with interpretation,” Jay Bain, sales and business marketing, at Sound Imaging, told HCB News. “Unfortunately, the technologist is unable to see the motion artifact until the image is complete, forcing a re-scan. Re-scans force the patient to stay in the MR suite for a longer time, which could increase patient anxiety. In addition, the patients scheduled for MRIs at a later time are now forced to wait longer for their scheduled appointment.”
Numed, a well established company in business since 1975 provides a wide range of service options including time & material service, PM only contracts, full service contracts, labor only contracts & system relocation. Call 800 96 Numed for more info.
Developed over a four-year period, the system was designed to address a range of issues affecting the MR team at Johns Hopkins Medical Center.
With SAMM MD, users can visually and audibly alert patients and MR technologists of any sign of motion, and enable MR technologists to see the patients in real time with MR-compatible HD video displays. They can also fully integrate patient work lists so patient videos are time-stamped and searchable to help reduce potential legal exposure.
Another feature only accessible to those with GE scanners is the stop-pause function, in which movement or motion by the patient is optionally paused during the MR scan to help increase patient safety, reduce repeat scans, and increase image quality.
Other capabilities include the recording of videos to help with technologist training for reducing claustrophobia and increasing patient safety; 24/7 remote/local alerts and recording of anyone who enters the MR room; and optional recording of patients during their entire scans from the moment they enter the MR room.
“We are always working on fine-tuning the motion and detection system, as well as constantly working on upgrading our video quality,” said Bain.
As part of the integration, special bulkhead adapters will need to be installed onto the penetration panel.
The hardware and software of SAMM MD is compatible with any MR system.
