 Abstract: Involuntary subject motion is a well-known problem in MR imaging. Motion simulation is an important step to evaluate correction performance and motion induced artifacts. Here we introduce a new approach based on MR tagging to simulate desired motion pattern on a plain phantom. We employed SPAMM method to generate grid tags with a specified orientation and position. Grid tags were rotated and shifted with a desired pattern per TR. Correspondingly, the imaging slice followed the pattern to compensate the rotation and translation of the tags. Employing this approach, we could simulate motion in 5 DOF.
