Ultrasonic beam forming method, device, ultrasonic equipment and storage medium

Abstract

The invention discloses an ultrasonic wave beam synthesis method, device, ultrasonic equipment and storage medium. The method includes: obtaining the original information matrix corresponding to the target pixel point; using K direction deflection filters to perform direction filtering on the original information matrix corresponding to the target pixel point to obtain K direction response feature matrices; according to the K direction response feature matrix , to determine the K target response feature matrices and the corresponding associated response feature matrices; according to the K target response feature matrices and the corresponding associated response feature matrices, K direction confidences are obtained; according to the K direction confidences corresponding to the target pixels and K target response feature matrices to obtain target echo signals; performing coherent superposition on the target echo signals to obtain synthetic echo signals corresponding to target pixels. The synthesized echo signal is a signal containing more real and effective information obtained after effectively filtering clutter, which helps to ensure the signal-to-noise ratio and resolution of the final ultrasonic image.

Description

technical field [0001] The present invention relates to the technical field of ultrasonic imaging, in particular to an ultrasonic beam forming method, device, ultrasonic equipment and storage medium. Background technique [0002] Ultrasound imaging is widely used in multidisciplinary medical practice to assist doctors in diagnosis and treatment. Generally speaking, the basis of modern medical ultrasound imaging systems is the Delay And Sum (DAS) beamforming imaging method. The basic principle is that first, the ultrasound probe is used to transmit ultrasound to human tissue, and then each array element of the ultrasound probe receives different time The echo signals of each array element are corrected for delay, and then coherently added to obtain a high-resolution ultrasonic image. In this process, the number of array elements of the ultrasound probe has a great influence on the effect of the final image, because each array element can obtain tissue information. The more a...
