Schematic showing how changes in axial position of a reflective structure, such as a lipoprotein granule, could cause subtle changes in the intensity of the detected reflection. This could cause a decorrelation, which would incorrectly be rendered as a flow signal. Similar changes in reflectivity could occur with transverse motion.
