Artifact reduction for EEG/fMRI recording part 1: nonlinear reduction of ballistocardiogram artifact
Objective: We present a new method to effectively remove ballistocardiogram artifacts (BAs) of electroencephalography (EEG), recorded inside a 1.5 T static magnetic field scanner, and conserve the time and frequency features of EEG activity. Methods: The BAs are approximated as deterministically chaotic dynamics. A wavelet-based nonlinear noise reduction (WNNR) method consisting of wavelet tran...
متن کاملBallistocardiogram artifact reduction in the simultaneous acquisition of auditory ERPS and fMRI.
Electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) are now being combined to analyze brain function. Confounding the EEG signal acquired in the MR environment is a ballistocardiogram artifact (BA), which is predominantly caused by cardiac-related body movement. The objective of this study was to develop and evaluate a method for reducing these MR-induced artifacts to ...
متن کاملCompressed Sensing for Motion Artifact Reduction
Introduction: Navigators can effectively track rigid-body motion of limited amplitude, such as respiratory motion [1,2,3]. In a Cartesian scan, data is corrected by applying to each k-space line the phase modulation corresponding to the amount of detected motion. However, lines associated with significant motion (e.g., swallowing in larynx imaging) are uncorrectable and therefore need to be dis...
متن کاملMadr : Metal Artifact Detection and Reduction
Metal in CT-imaged objects drastically reduces the quality of these images due to the severe artifacts it can cause. Most metal artifacts reduction (MAR) algorithms consider the metal-affected sinogram portions as the corrupted data and replace them via sophisticated interpolation methods. While these schemes are successful in removing the metal artifacts, they fail to recover some of the edge ...
متن کاملMoving GLM ballistocardiogram artifact reduction for EEG acquired simultaneously with fMRI.
OBJECTIVE Simultaneous acquisition of electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI) enables studies of brain activity at both high temporal and high spatial resolution. However, EEG acquired in a magnetic field is contaminated by ballistocardiogram (BKG) artifact. The most commonly used method of BKG artifact reduction, averaged artifact subtraction (AAS), was not ...
