Prospective head motion correction using FID-guided on-demand image navigators.
PURPOSE We suggest a motion correction concept that employs free-induction-decay (FID) navigator signals to continuously monitor motion and to guide the acquisition of image navigators for prospective motion correction following motion detection. METHODS Motion causes out-of-range signal changes in FID time series that, and in this approach, initiate the acquisition of an image navigator. Co-...
متن کاملMotion Correction in Magnetic Resonance Imaging Using the Signal of Free-Induction-Decay
Magnetic resonance imaging (MRI) is highly susceptible to subject’s motion and can significantly degrade image quality. In brain MRI exams, involuntary headmovements can affect the sampled k-space data. Such unintended alterations may result in visible image artifacts such as blurring, ghosting and others, and therefore potentially disqualify the image fromdiagnostic purposes. Methods to charac...
متن کاملHybrid Prospective & Retrospective Head Motion Correction System to Mitigate Cross-Calibration Errors
INTRODUCTION – Correction of head motion artifacts is essential for clinically acceptable image quality. This is especially important for long scans, such as DTI, fMRI, and high-resolution structural scans. Prospective motion-correction using stereovision systems [1,2] have been suggested to perform real-time head motion-correction without necessitating the acquisition of additional MR-based na...
متن کاملMotion correction in simultaneous PET/MR brain imaging using sparsely sampled MR navigators: a clinically feasible tool
BACKGROUND We present a study performing motion correction (MC) of PET using MR navigators sampled between other protocolled MR sequences during simultaneous PET/MR brain scanning with the purpose of evaluating its clinical feasibility and the potential improvement of image quality. FINDINGS Twenty-nine human subjects had a 30-min [(11)C]-PiB PET scan with simultaneous MR including 3D navigat...

Fig. 2 Uncorrected (black) and corrected (blue) navigator signal of an MP-RAGE measurement. Head position was changed during the period marked violet. The green bars show motion threshold at that moment, red points mark motion-corrupted TRs, which are rescanned at the end (pink bar). Cyan shows the online regression time course.
