The acoustic pressure profile along the axis of the carotid artery determined by an in situ pressure calibration using a broadband hydrophone. The peak-to-peak acoustic pressure at the axial center of the thrombus (inset) was 0.48 MPa, diminishing to roughly 0.34 MPa at the upstream and downstream faces of the thrombus. Porcine plasma flows in the positive direction.
