description | The invention discloses an ultrasonic scatterer diameter multi-scale imaging method based on a back-scattering coefficient. According to the method, the back-scattering coefficient is computed based upon an ultrasonic radio-frequency signal, and then ultrasonic scatterer diameter parameters and an ultrasonic scatterer diameter multi-scale image are computed. Sliding windows of different scales slide on the ultrasonic radio-frequency signal, and the ultrasonic scatterer diameter parameter in each sliding window is computed based upon the back-scattering coefficient, so that ultrasonic scattererdiameter parameter matrices of various scales are obtained; a multi-scale ultrasonic scatterer diameter parameter matrix is obtained by superposing and averaging ultrasonic scatterer diameter parameter matrix inserts which are taken as strength of the ultrasonic radio-frequency signal; and the multi-scale ultrasonic scatterer diameter parameter matrix undergoes color mapping, so that the ultrasonic scatterer diameter mul |
