Abstract :
In this paper, a novel trace algorithm for tissu movement for two dimensional ultrasound image sequences is proposed, each ROI (region of interest) of the preferred image is divided into 16 sub areas, each gravity center of each sub area is calculated in adjacent images, which is used to determine the new positions of the 16 sub ROIs in the next frame, and the traced tissue position can be determined using SAD algorithm, compared with the traditional block match trace algorithm, our method is efficient and stable, especially for the deformation tissue tracking.
