ScanLabMR unveils MRI simulation upgrade enabling realistic artefact visualisation

MRI and CT simulation and education software specialist ScanLabMR has made an upgrade to its MRI simulator that it says introduces the industry’s first scientifically accurate visualisation of key image artefacts within a simulated clinical environment. The capability allows users to observe and interact with artefacts as they occur during scanning, most notably phase aliasing, also known as wrap artefact.

Phase aliasing is one of the most frequently encountered artefacts in clinical MRI practice. “Until now, MRI simulation platforms have been limited in their ability to realistically demonstrate how parameter choices directly impact image outcomes,” the company says. The enhanced simulator now dynamically displays varying degrees of phase aliasing directly within generated MR images. The amount of wrap experienced by the user is determined by a true cause-and-effect relationship between key imaging parameters, including field of view selection, oversampling/wrap prevent/no phase wrap settings and phase encoding direction choices.
