Figure 7
X-ray PIV results showing recirculating blood flow in a glass capillary, captured with the use of the linear VCA shutter. The schematic of the capillary is overlaid with the velocity vector field and streamlines. The recirculation is caused by rapid injection of a bolus of contrast agent immediately before imaging. The experiment was conducted at SPring-8 (Japan) on the BL20XU beamline, and is only possible with reduced dose to the sample to prevent cell damage and clotting. The analysed images were captured at 3 ms exposures, at an instantaneous frame rate of 300 frames s−1 for each image pair.
