Segmenting electroencephalography wires reduces radiofrequency shielding artifacts in simultaneous electroencephalography and functional magnetic resonance imaging at 7 T.

"this simplified model provides a similar transmit field distribution compared to more detailed models (supporting information s8 in data s1 ).; the coil provides a circularly polarized excitation at 297 2 mhz with a decoupling between neighboring elements from -8 3 to -14 3 db which is similar to the physical coil a detailed description of the rf coil modeling is in the supporting information s1 in data s1 .; the latter was digitized based on anatomical images and measured dielectric properties (supporting information s2 in data s1 ).; the segmented eeg cap was also simulated on the female ella realistic human model revealing similar reduction of the rf shielding effects upon addition of the segmentation resistors (supporting information s5 in data s1 )."
