Abstract

The embodiment of the invention provides a medical image processing method, device and equipment. The method comprises the steps: obtaining a first medical image and a second medical image of a specified target; registering the second medical image to the first medical image based on a first spatial transformation model, and obtaining a first registering image; registering the first registering image to the first medical image based on a second spatial transformation model through an unsupervised deep learning method, obtaining a second registering image, and enabling the fine structures in the specified target to be aligned through the registering of the unsupervised deep learning method, thereby reducing the artifacts, and improving the precision of the registering result. Especially for a tissue comprising many fine structures, the method can obtain a better registering result, and solves a problem to certain degree that the precision of a registering result is lower for the tissue comprising many fine structures in the prior art.

Description

[0001] 【Technical field】 [0002] The present solution relates to the field of medical image processing, in particular to a medical image processing method, device and equipment. [0003] 【Background technique】 [0004] Medical imaging technology is one of the more active research fields in medical radiology, and X-ray imaging technology is the main technology of medical imaging. In digital X-ray imaging technology, indirect digital X-ray imaging (Computed Radiography, CR) and digital radiography (Digital radiography, DR) combine computer digital image processing technology and X-ray radiation technology at the same time, with low radiation dose, high image quality, It has the advantages of high detection rate of disease and high accuracy of diagnosis. . [0005] In applications, it is often necessary to perform registration processing on medical images acquired at different times of the same target. Existing medical image registration mostly adopts rigid body registration o...
