Abstract：In order to achieve early diagnosis of breast lesions and improve imaging resolution and accuracy,this paper pro-poses a feature extraction algorithm based on ultrasound transmission imaging.The research mainly includes placing the breast mod-el at the center of a ring array,controlling the ring array to collect ultrasound transmission signals,selecting signal attenuation and signal flight time difference as inversion parameters to construct an ultrasound feature matrix,extracting edges from the ultrasound feature matrix,removing singular values,and then imaging through a filtered backprojection algorithm.Quantitative analysis of the sound velocity,attenuation,and size of the imaging results shows that this method can improve imaging resolution and accuracy.
