Noise covariance matrices from representative healthy 32-year-old female participant.

Caption

Noise covariance matrices for 8-channel (left), 16-channel AIR (middle), and 32-channel (right) head coils. Noise power of each individual element is shown along diagonal, and noise correlation between elements is shown on off-diagonal. Off-diagonal terms are normalized to diagonal term, because relationship of off-diagonal to diagonal terms reflects coupling.
