Results to evaluate the primary frequency components of the cerebral spinal fluid (CSF) motion propagation. (a) Velocity waveforms are shown at various tissue regions indicated by color squares on T2 image (c). (b) Power spectra of those waveforms normalized by each peak are exhibited. Although the shape of the velocity waveforms appears to be different, the principal frequencies agree each other.
