Self-navigated prospective motion correction of repeated 3D-EPI acquisitions for functional MRI applications
… over threedimensional (3D)-EPI as it is more motion robust. However, 3D-EPI offers various advantages over 2D-EPI for functional MRI (fMRI), including the absence of spin-history artifacts, potential for faster acceleration, and better signal quality at higher spatial resolution. As such, …

Implementation of anatomical navigators for real time motion correction in diffusion tensor imaging
Prospective motion correction methods using an optical system, diffusion-weighted prospective acquisition correction, or a free induction decay navigator have recently been applied to correct for motion in diffusion tensor imaging. These methods have some limitations and drawbacks. This article …

Online, low-latency decision making for Fetal Magnetic Resonance Imaging with machine learning
… of HASTE images routinely suffer from fetal motion which leads to image artifacts, incomplete brain coverage as well as longer scan times. To address this problem, interleaved 3D Echo-planar Imaging (EPI) navigators are acquired along with HASTE images, which can provide pose information for …

Improving Data Quality for High Resolution Functional MRI in Cognitive Neuroscience Applications
… MRI scanners. Firstly, I studied the effect of Prospective Motion Correction (PMC) on 3T data using a simple visual paradigm. In contrast to most conventional techniques that use retrospective motion correction (RMC), PMC collects real-time motion data and uses it to update the acquisition field …
