Abstract
An ultrasound system determines the relative movement in a first direction (F,) of first matter, such as blood flow, and second matter, such as an artery wall, in a subject under study (S). A beam (B,) of ultrasound waves defining a plurality of beam positions (BP,and BP,) and beam axes (A,and A,) are moved in scan directions having components parallel to direction F,. First and second blocks of data representing the first and second matter, respectively, are generated. A processor (,) performs an estimation of speckle size on first data to obtain a first result, and performs analysis of the second block of data to obtain a second result. The two results are analyzed to obtain a measure of the relative movement of the first and second matter.
