Artifacts caused by patient motion during scanning remains a serious problem in most MRI applications, with unsedated pediatric MR imaging being a notable example. Multiple approaches have been investigated in the past two decades mainly focusing on 2D motion. However these methods are limited by subject through-plane motion. The 3D PROspective MOtion correction system (PROMO) attempts to address the issue by correcting for both in-plane and through-plane motion. In this study, we quantified the improvements in the image quality in patients with varying amount of in-scanner motion during PROMO on and off scans.
