Patient movement, and subsequent artifacts, have been a long standing challenge in the world of imaging. Despite the advances in imaging, such as corrective software and 3D navigators, motion artefacts still exist.
Research conducted by Maxim Zaitsev, Ph.D, Julian Maclaren, Ph.D and Michael Herbst, Ph.D, provided a toolbox of methods to use for correcting artifacts within imaging. While simply stopping motion provides the best results for imaging, it is not always practical. Methods such as general anesthesia, limited motion artifacts to about 12% of cases with pediatric patients. However, with anesthesia, comes more health risks and greater costs. Methods also include asking the patient to hold their breath for abdomen and cardiac imaging. Again, this comes with limitations; scans can only last for 20-22 seconds since patients cannot usually hold their breaths much longer than this time frame.
While there are countless methods to prevent and limit patient movement and correct artifacts, a simpler method exists. At Sound Imaging, we offer SAMM M.D., a MR-compliant CCTV system that works to improve imaging and reduce artifacts. This system allows technologists to monitor patients in the bore, and to automatically stop the scan if patient motion is detected; this feature saves time and money for your facility. We also offer a number of coils, parts, repairs, and systems for any other imaging need.
