Figure 5

IVPA-US imaging of pulsatile motion at different speeds. Four consecutive IVPA-US frames selected at speed of (a) 1 fps, (b) 5 fps, (c) 10 fps, and (d) 16 fps highlighting the imaging distortion induced by pulsatile motion at lower imaging speed, while demonstrating the capability to suppress the motion artifacts at 16 fps. Complete comparison of IVPA-US imaging results at different imaging speed (1, 5, 10, 16, 20, and 25 fps) can be found in Supplementary Video S3. The depth field of view is 5.09 mm. Scale bar: 1 mm.
