Increased brain coverage and efficiency when measuring current-induced magnetic fields by use of simultaneous multi-slice echo-planar MRI
Fig 5
Results from the ΔBz,c measurements in the human brain for a 2-mA current loop around the head.
The relative position of the slices and loop placement are shown in Fig 1E-1G. A) Root Mean Square (RMS) error between the measured (ΔBz,c2mA) and simulated (ΔBz,csim) current-induced magnetic fields. Results are shown for multi-slice measurements with different multiband (MB) factors and interslice gaps, and the corresponding single-slice (SS) measurements. Each data point and vertical error bar represent the average and standard deviation across subjects. B) Comparison between a multi-slice acquisition with a MB factor of 5 and an interslice gap of 12 mm, and corresponding single-slice acquisitions. Left: simulated and measured magnetic fields. Right: differences between the measured and simulated fields.
