Acceleration and enhancement methods and system for ultrasound scatterer structure visualization

摘要

The present invention provides an acceleration and enhancement methods for ultrasound scatterer structure visualization. The method includes: obtaining an ultrasonic image, calculating all values of the ultrasonic signal points in each mth window centered at a nth signal point to obtain a plurality of original statistical values anxm, obtaining a plurality of mth statistical values by averaging value of original statistical values in the same window, calculating a plurality of mth weighting values based on the statistical values by different weighting formulas, multiplying each weighting value with the original statistical values corresponding to the various size of windows, summing up to obtain an ultrasound structure scatterer value of the nth ultrasonic signal point, and generating an ultrasound scatterer structure image based on a matrix of the ultrasound scatterer values. The present invention further combined interpolation method can reduce the computation time and retain the 80% accuracy.
