A processing method and device for ultrasonic wide-field imaging

Abstract

The invention relates to an ultrasonic wide-view imaging processing method and device. The ultrasonic wide-view imaging processing method includes the following steps: collecting ultrasonic images, and storing the ultrasonic images in the order of the collecting time; obtaining one ultrasonic image, and judging whether the obtained ultrasonic image is the first frame of image or not; if the obtained ultrasonic image is the first frame of image, enabling the ultrasonic image to serve as a reference image, and carrying out outputting; if the obtained ultrasonic image is not the first frame of image, enabling the ultrasonic image to serve as a floating image; determining a search region of feature points of the floating image in the reference image according to the scanning speed of the prior frame of image and the conversion coefficient of the prior frame of image; searching the search region for the matched feature points, calculating the scanning speed of the current image, splicing the floating image with the prior image, and carrying out outputting. By means of the technical scheme, the matching speed of the ultrasonic images can be effectively increased, the matching accuracy of the ultrasonic images can be effectively improved, the wide-view imaging processing speed is accordingly increased, and the wide-view imaging processing efficiency is accordingly improved.

Description

technical field [0001] The invention relates to an imaging processing method, in particular to a processing method and device for ultrasonic wide-view imaging. Background technique [0002] Medical ultrasound imaging, which has the advantages of non-invasive and economical, is the preferred method for disease diagnosis and is widely used in clinical practice. But ultrasound imaging can only produce images with a small field of view, preventing doctors from seeing entire organs in a single ultrasound image. Using image stitching technology, the images being scanned are seamlessly stitched together to provide a wider field of view, which is beneficial to doctors' observation and diagnosis. In the wide-view imaging mode, as the probe scans forward along the detection area, a panoramic image is finally obtained by sequentially splicing the stitched image of the previous frame and the image obtained by the current scan. Compared with traditional ultrasound images, this image ha...

Problems solved by technology

Its defect is that the search length along the moving direction of the probe is fixed or estimated according to the horizontal offset of the previous registration, and the corresponding search length is not set by the moving speed of the probe, and cannot be within a range as small as possible and large enough The matching feature points are found, which causes the registration process to be time-consuming or the registration accuracy is not high
