Head pose prediction for prospectively-corrected EPI during rapid subject motion

چکیده
INTRODUCTION Prospective motion correction using an external tracking device is an effective technique for motion correction in fMRI [1]. It has advantages over image-based correction methods [2], which require full volume coverage to compute motion parameters in a full six degrees of freedom (6DOF). The ultimate goal of this project is to use prospective correction to perform fMRI experiments during significant head motion. However, when motion is rapid, latency delays in the system lead to significant slice misregistration. The aim of this work is to determine whether motion prediction can mitigate this problem.

Towards combining prospective motion correction and distortion correction for EPI
Introduction: In most fMRI studies, subject motion is assumed to be restricted to such a small amount that susceptibility-induced distortions can be treated as stationary and independent from motion. However, the ultimate goal of this project is to enable fMRI studies during significant head motion by applying prospective motion correction techniques [1]. In this regime, the motion dependence o...
متن کاملReal-Time Intra-Volume Motion Correction in EPI Using Active Markers
Introduction: Echo-planar imaging (EPI) is the sequence of choice for functional MRI (fMRI), where rapid scanning is needed in order to continuously acquire complete brain volumes for a time-series analysis. Even a few millimeters of movement during an fMRI scan can result in large, artifactual, signal changes in the timeseries data that will obscure the relatively small brain activation signal...
متن کاملConcurrent correction of geometric distortion and motion using the map-slice-to-volume method in echo-planar imaging.
The accuracy of measuring voxel intensity changes between stimulus and rest images in fMRI echo-planar imaging (EPI) data is severely degraded in the presence of head motion. In addition, EPI is sensitive to susceptibility-induced geometric distortions. Head motion causes image shifts and associated field map changes that induce different geometric distortion at different time points. Conventio...
متن کاملMotion correction for functional MRI with three‐dimensional hybrid radial‐Cartesian EPI
PURPOSE Subject motion is a major source of image degradation for functional MRI (fMRI), especially when using multishot sequences like three-dimensional (3D EPI). We present a hybrid radial-Cartesian 3D EPI trajectory enabling motion correction in k-space for functional MRI. METHODS The EPI "blades" of the 3D hybrid radial-Cartesian EPI sequence, called TURBINE, are rotated about the phase-e...
متن کاملSuppressing Respiration Effects when Geometric Distortion Is Corrected Dynamically by Phase Labeling for Additional Coordinate Encoding (PLACE) during Functional MRI
Echo planar imaging (EPI) suffers from geometric distortions caused by magnetic field inhomogeneities, which can be time-varying as a result of small amounts of head motion that occur over seconds and minutes during fMRI experiments, also known as "dynamic geometric distortion". Phase Labeling for Additional Coordinate Encoding (PLACE) is a promising technique for geometric distortion correctio...
