Abstract:
Methods and non-transitory computer readable media that store executable instructions to perform a method for reducing motion artifacts in shear wave measurements are presented. Accordingly, reference pulses are delivered to a common motion tracking location (CMTL) and a plurality of target locations in a region of interest (ROI) to detect corresponding initial positions. Further, a shear wave is generated and tracked in the ROI using tracking pulses delivered to the CMTL and the plurality of target locations for determining corresponding displacements. Additionally, an average displacement of the CMTL is computed. Further, a motion corrected displacement for a target location in the plurality of target locations is estimated based on a displacement of the target location at a particular time, a corresponding displacement of the CMTL measured proximate in time to the measurement of the displacement of the target location and the average displacement of the CMTL.
