A 128 x 128 activation map for a slice of an fMRI phantom and an anatomical reference.
1 |
a 128 x 128 x 2 array with the
first slice an activation map for an MRI phantom and the second an
anatomical overlay. NA
values are outside the surface. The
activation map (hoffmanphantom[,,1]
) is 1 if activated,
0 otherwise. The second layer (hoffmanphantom[,,2]
)
indicates the anatomical structure. Approximately 3.8 percent of the
pixels are activated in this slice.
