Cardiac vectors in the healthy human fetus: developmental changes assessed by magnetocardiography and realistic approximations of the volume conductor

2013 Physiological Measurement  
To achieve this objective, we rely on a recently developed methodology for fetal cardiac vector estimation, using multichannel fetal magnetocardiographic (fMCG) recordings and realistic approximations  ...  This study sought to characterize the developmental changes of three measures used to describe the morphology of the fetal cardiac vector: QRS peak-amplitude, QRS duration and QRS timeamplitude integral  ...  Acknowledgments Authors would like to thank the study coordinator JoAnn Lierman. RNC, PhD.  ...

Modeling & Analysis

2003 NeuroImage  
Results Discussion We demonstrate an approach for applying ICA to group fMRI data such that the delay of the hemodynamic response does not affect the separability of the sources.  ...  Such a model is also important to prevent artifactual separation of a source into multiple components due to the delay.  ...  Fisher's linear discriminant is applied to feature vectors for classification.  ...
