    Example of functional MR imaging activation, in one subject after visual stimulation (checkerboard, 8 Hz), superimposed on an anatomic image (MP-RAGE). Pixels with a z-score above 4.0 are coded as to the bar on the right. Top row shows runs 1 and 2 from session 1 with system B, middle row shows both runs from session 2 with system A, and bottom row shows the runs from session 3 with system B.

    Fig 2.

    Averages for the reproducibility measures D, Rsize, and Roverlap for same-session and intersession reproducibility for system A and system B, and intermachine reproducibility. D is the distance between the centers of the activated areas, Rsize is the ratio of the volumes of activated areas, and Roverlap is the ratio of the common activated areas. Rsize and Roverlap must be read from the left y axis, and D must be read from the right y axis where the order is inverted.

    Fig 3.

    Averages for the reproducibility measure D, separated for the frequency- and phase-encoding directions and the section direction, for same-session and intersession reproducibility for system A and system B, and intermachine reproducibility. D is the distance between the centers of the activated areas.
