A Preprocess Method of External Disturbance Suppression for Carotid Wall Motion Estimation Using Local Phase and Orientation of B-Mode Ultrasound Sequences

Figure 12

Wall motions estimated from a ten-second clinical B-mode ultrasound image sequence in longitudinal (a) and radial (b) directions after disturbance rejection processing. The disturbance rejections are based on the estimated disturbances demonstrated in Figure 12 which are obtained by the BM (blue), PM (cyan), SBM (magenta), SPM (yellow), SWBM (green), SWOM (gray), SWPM (orange), and SWPOM (black) methods.
