Indoor Positioning System Using Magnetic Field Map Navigation and an Encoder System [PDF]
Sensors, 2017 In the indoor environment, variation of the magnetic field is caused by building structures, and magnetic field map navigation is based on this feature. In order to estimate position using this navigation, a three-axis magnetic field must be measured at ...

Regularized Field Map Estimation in MRI [PDF]
IEEE Transactions on Medical Imaging, 2008 In fast magnetic resonance (MR) imaging with long readout times, such as echo-planar imaging (EPI) and spiral scans, it is important to correct for the effects of field inhomogeneity to reduce image distortion and blurring. Such corrections require an accurate field map, a map of the off-resonance frequency at each voxel.

Using synthetic MR images for distortion correction
Developmental Cognitive Neuroscience, 2023 Functional MRI (fMRI) data acquired using echo-planar imaging (EPI) are highly distorted by magnetic field inhomogeneities. Distortion and differences in image contrast between EPI and T1-weighted and T2-weighted (T1w/T2w) images makes their alignment a ...
