The invention discloses an ultrasonic imaging space composite method, a device, an ultrasonic diagnostic instrument and a storage medium. The method includes: acquiring at least two original ultrasonic images with different angles in the current cycle, determining a reference ultrasonic image and an ultrasonic image to be corrected; performing motion estimation on the ultrasonic image to be corrected and the reference ultrasonic image, and determining a target velocity vector; according to the target velocity vector, Calibrate the ultrasonic image to be corrected, obtain the target corrected ultrasonic image, determine the target corrected ultrasonic image and the reference ultrasonic image as the ultrasonic image to be compounded; perform texture analysis on each ultrasonic image to be compounded, and obtain the target texture feature; Image reliability analysis is performed to obtain target matching weights; spatial compounding is performed according to target texture features and target matching weights corresponding to all ultrasonic images to be compounded, and target compound ultrasonic images corresponding to the current cycle are obtained. The method can improve the resolution of the target composite ultrasound image obtained by spatial composite.
Description
technical field [0001] The invention relates to the technical field of ultrasonic imaging, in particular to a method, device, ultrasonic diagnostic instrument and storage medium for spatial compounding of ultrasonic imaging. Background technique [0002] Spatial compounding is an important part of the modern ultrasound imaging process. Due to the scattering characteristics and wavelength size of ultrasound, a large amount of speckle noise will be generated when ultrasound is imaged in human tissue. These speckle noises are the result of coherent superposition of ultrasound and contain real information about human tissue, but affect the visual observation of ultrasound imaging. In order to reduce the interference of speckle noise and improve the resolution of ultrasound images, spatial compounding technology is needed to improve the image quality of ultrasound images. [0003] Spatial composite technology mainly refers to obtaining multiple ultrasound images with subtle dif...
