Super-resolution scan conversion method, device, ultrasonic equipment and storage medium

Abstract

The invention discloses a super-resolution scanning conversion method, device, ultrasonic equipment and storage medium. The method includes: performing a geometric search based on the actual physical position relationship, determining the polar coordinate index corresponding to each pixel position in the image display area on the display screen; acquiring N frames of ultrasonic images to be processed based on the polar coordinate system; The ultrasonic image and the N-1 frame buffer ultrasonic image are registered and corrected to obtain N frames of corrected ultrasonic images; the structure tensor analysis is performed on each corrected ultrasonic image, and the target structure tensor matrix corresponding to the corrected ultrasonic image is obtained; the current ultrasonic image is used , analyze the reliability of each corrected ultrasound image, and obtain the corresponding reliability weight of the corrected ultrasound image; according to the target structure tensor matrix and reliability weight corresponding to the same pixel position in N frames of corrected ultrasound images, the gray value of the pixel is calculated Composite to acquire the target ultrasound image. This method can effectively guarantee the image resolution of the target ultrasound image.

Description

technical field [0001] The invention relates to the technical field of ultrasonic imaging, in particular to a super-resolution scan conversion method, device, ultrasonic equipment and storage medium. Background technique [0002] Digital scan conversion is a necessary step in the current ultrasound imaging technology, mainly used to transform the image data from the polar coordinate system based on the ultrasound probe to the rectangular coordinate system corresponding to the display screen of the ultrasound equipment, so that the display screen of the ultrasound equipment can be Accurately display ultrasound images. Understandably, the main reason why digital scan conversion is a necessary step in current ultrasound imaging technology is that ultrasound imaging is an imaging system based on scan lines, and each scan line starts from the position of the ultrasound probe and is perpendicular to the surface of the ultrasound probe. A straight line with intervals between all s...
