Problems solved by technology

However, when there is a large body position deviation between the two images, the registration through the above process will reduce the registration accuracy, and even lead to registration failure, so the robustness of the existing image registration methods is poor

Embodiment Construction

[0020] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0021] In one embodiment, such as figure 1 As shown, an image registration method is provided, and the method is applied to a processor capable of image registration as an example for explanation. The method includes the following steps:

[0022] Step S100, acquiring the original floating image and the reference image to be registered.

[0023] In the process of image registration, the image that undergoes image transformation processing is called a floating image, and the image that remains unchanged is called a reference image. Since the floating image and the referenc...

Abstract

The invention relates to an image registration method, a storage medium and computer equipment. When the body position directions of the original floating image and the reference image are inconsistent; image registration is not directly carried out, orientation correction is firstly carried out on the original floating image by means of the direction correction image with the same body position direction as the reference image, and then image registration is carried out, so that the orientation consistency of the registered image can be ensured, the registration precision is improved, and therobustness of the image registration method is better.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image registration method, storage medium and computer equipment. Background technique [0002] With the continuous development of medical imaging, medical image analysis has become a very important content of clinical diagnosis, and the problem of medical image registration has been gradually raised, and has become one of the hot topics in the field of medical image research. Medical image registration refers to finding a certain spatial transformation to make the corresponding points of the two images completely consistent in terms of spatial position and anatomical structure, and the result of the registration is required to make all the anatomical points on the two images All points with diagnostic significance as well as surgical regions were matched. [0003] In the prior art, in the process of image registration, for the image data in a set of image ...
