CBSI method improves the spatial signal quality. (a) CNR map of original oxy-Hb of subject 4 in the FB block. We see that while the contrast correctly localized left motor cortex, the activation is diffuse. (b) CNR map of corrected activation signal for subject 4 in the FB block. Compared to the uncorrected map, the corrected map is much more localized and similar to the map in the FO block (c). The CNR maps are normalized to the maximum and minimum across all channels within each map. Numbers in white indicate the channel number. The spatial maps are smoothed using spline interpolation.
