PARAMETER MAPPING FOR THE DETECTION OF DISTURBED BLOOD-FLOW

Particularly in color flow mapping, the detection of minor stenoses is a significant outstanding challenge, With the goal of spatially mappi ng changes in velocity and shear rate to locate the source of the Bow disturbance, two indicators of the magnitude of the signal correlation are presented and evaluated for known experimental flow conditions, A normalized parameter is presented, which is proportional to the magni tude of the signal correlation evaluated over a set of received pulses , Its performance is compared to that of a single-lag correlation meas ure for the development of spatial maps that indicate shear rate and v elocity.
