Figure 3From: Development of a theoretical framework for analyzing cerebrospinal fluid dynamicsDPIV volume change estimation technique. Sagittal MR images at two different times, with Digital Particle Image Velocimetry (DPIV) derived displacement vectors along the lateral ventricle's walls. The vector lengths have been magnified for clarity. Vector color is based on wall normal displacement: red represents distension, blue contraction, and green nominal normal displacement.Back to article page
