Correlation mapping technique composed of delay time and correlation coefficient mapping to characterize propagation properties of cerebrospinal fluid (CSF) motion was applied to young, elderly healthy and idiopathic normal pressure hydrocephalus (iNPH) patient groups for classification. Brightness of the color of maximum correlation map was adjusted according to the amplitude of the CSF velocity waveform for assisting clinicians to understand the propagation properties intuitively. The groups were classified by quantifying the standard deviation of the correlation distributing in the intracranial CSF space. The technique was expected to classify diseases related to CSF dynamics such as iNPH.
