Electrocardiographic artifact is generally considered to be a nuisance. Respiratory artifact, however, is a physiologic signal that may carry useful diagnostic information. Our goal was to evaluate the characteristics, prevalence, and clinical significance of respiratory artifact observed in electrocardiograms (ECGs). ECGs exhibiting repetitive microoscillations were systematically collected. T...
The benefits of four-dimensional computed tomography (4D CT) are limited by the presence of artifacts that remain difficult to quantify. A correlation-based metric previously proposed for ciné 4D CT artifact identification was further validated as an independent artifact evaluator by using a novel qualitative assessment featuring a group of observers reaching a consensus decision on artifact lo...
Combined EEG/fMRI recording has been used to localize the generators of EEG events and to identify subject state in cognitive studies and is of increasing interest. However, the large EEG artifacts induced during fMRI have precluded simultaneous EEG and fMRI recording, restricting study design. Removing this artifact is difficult, as it normally exceeds EEG significantly and contains components...
