1. A method for ultrasound scatterer structure visualization, comprising: obtaining an ultrasonic image signal, wherein the ultrasonic image signal comprises a plurality of ultrasonic signal points, each ultrasonic signal point comprises a value; defining a first window, wherein a central point of the first window is a first ultrasonic signal point; calculating a plurality of values of the ultrasonic signal points in the first window to obtain a first original statistical value a 1 x 1 ; moving the central point of the first window to a second ultrasonic signal point, calculating a plurality of values of ultrasonic signal points in the first window to obtain a second original statistical value a 2 x 1 , wherein an interval between the first ultrasonic signal point and the second ultrasonic signal point is one signal point; calculating a plurality of values of ultrasonic signal points in the first window centered at different ultrasonic signal points, obtaining a n th original statistical value a n x 1 until the first window is moving throughout all ultrasonic signal points, wherein the interval between two adjacent ultrasonic signal points is one signal point; calculating a first statistical value by averaging the original statistical value s a 1 x 1 , a 2 x 1. .. a n x 1 ; calculating a second statistical value to a m th statistical value based on various size of the windows; calculating a first weighting value to a m th weighting value based on the plurality of statistical values; calculating an ultrasound scatterer structure value of the first ultrasonic signal point based on multiplying each weighting value with the original statistical values corresponding to the various size of windows, and summing up; calculating the plurality of ultrasound scatterer structure values from the second ultrasonic signal point to the n th ultrasonic signal point; and generating an ultrasound scatterer structure image based on a matrix of the ultrasound scatterer structure values.
