Author response image 2. Raw EPI-images of six example subjects.
The images depict the full field of view covered by our measurements. Aliasing artifacts occur when the dimensions of an object exceed the imaging field-of-view, but are within the area covered by the receiver coil. This “wrap-around artifact” is evident as a folding over of surrounding parts into the area of interest, and it is most severe along the phase-encode dimension. In our measurement, the phase-encode dimension was the anterior-posterior axis. No wrap-around artifacts are evident in any of the examples, nor in the other image data that were part of this data set.
