Flow visualization using fluorescent particle tracking by high-speed microscopy in catheter. Pathlines of fluorescent particles illustrate the entry of a flow, followed by the confluence of flows in the lumen. The Reynolds number is 0.5. The plane of focus of the microscope objective was located to the middle plane of the catheter. Scale bar is 200 μm.
