Abstract

The present invention is applicable to the field of computer technology, and provides an ultrasonic imaging method, device, equipment, and storage medium based on ultrasonic RF signals. The method includes: receiving and collecting ultrasonic echo radio frequency signals, In the depth direction of the image, the original ultrasound image is layered to obtain multiple layered images, and each layered image is denoised to extract the corresponding layered blood flow image from each layered image. Each layered blood flow image is interpolated to obtain a high-resolution interpolated image after interpolation, and the high-resolution interpolated images are superimposed and reconstructed into one image to obtain a high-resolution ultrasonic image corresponding to the ultrasonic echo radio frequency signal, and finally the ultrasonic echo High-resolution ultrasound images corresponding to wave radio frequency signals, thereby improving the reconstruction effect of blood vessel images.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an ultrasonic imaging method, device, equipment and storage medium based on ultrasonic RF signals. Background technique [0002] The distribution of blood vessels in various organs of the human body is an important indicator for clinical diagnosis of some lesions. Currently, the main blood flow imaging methods include CT angiography (CTA), magnetic resonance angiography (MRA), digital subtraction angiography (DSA), and ultrasound Doppler imaging (CDFI). Because CT and X-rays have certain radiation hazards to the human body, while ultrasound has the advantages of non-invasiveness, safety, fast imaging speed, and convenient use, so ultrasound imaging is widely used in clinical diagnosis and is one of the important tools for clinical diagnosis. . Currently, ultrasound imaging systems are based on emitting focused ultrasound to improve image quality. A comple...
