Image registration method, wide-field imaging method, ultrasonic imaging method and system thereof

Abstract

The invention discloses an image registration method, a panoramic imaging method, an ultrasonic imaging method and systems thereof. All the methods comprise the following basic steps: determining a floating chart and a registration chart; dividing out a plurality of subregions in the floating chart; determining a characteristic point in each subregion; determining the search region of each characteristic point in the registration chart; calculating the motion vector of each characteristic point relative to the registration chart; carrying out fitting on the motion vector to obtain the transformation coefficient of floating chart relative to the registration chart; and splicing to obtain a panoramic image through the transformation coefficient. The methods disclosed by the invention can accurately and rapidly conduct image registration to form the panoramic image.

Description

[0001] technology neighborhood [0002] The present invention relates to the technical field of image stitching in medical ultrasound systems, in particular to an image registration method and its system, a wide-view imaging method and its system using the image registration method and its system, and a wide-view imaging method using the same. Methods and Systems Thereof Ultrasound imaging methods and systems therefor. Background technique [0003] Ultrasonic wide-view imaging technology uses a series of two-dimensional slice images collected by moving the probe in the same plane to stitch together a wide-view image with a larger observation field, so that the complete tissue and structure can be displayed on the same image, which is convenient for doctors to diagnose . [0004] Ultrasound instruments are generally used by doctors to observe the internal tissue structure of the human body. The doctor places the operating probe on the skin surface corresponding to the part of ...

AI Technical Summary

Problems solved by technology

[0006] 1. In the case of ensuring accuracy, the amount of calculation is very large, resulting in slow imaging speed;

[0007] 2. Due to the influence of factors such as ultrasonic image noise, tissue movement and operation techniques, the algorithm has poor fault tolerance
