Ultrasonic imaging method and apparatus

Abstract

Disclosed is an ultrasonic imaging method. The method includes: on a basis of performing fuzzy segmentation of a membership function on an echo signal, sequentially dividing an input image into a plurality of fuzzy segments according to a strength of an echo; dividing the image into a plurality of layers accordingly; and performing a spatial neighborhood operation on a membership degree value in the plurality of layers, so as to obtain a space fuzzy segmentation array; in another aspect, determining a manipulated variable vector of the image according to image content-based self-adaptive calculation or user-based input, flexibly weighting and stretching space fuzzy segmentation arrays at the layers according to the manipulated variable vector finally, and adjusting and compounding the input image by using obtained echo increment and brightness compensation, so as to obtain a final output image. Also disclosed is a corresponding ultrasonic imaging apparatus.
