Problems solved by technology

Because the difference between the subject's shooting posture (such as lying position and angle) and the subject's state (such as the difference between full and empty stomach in the stomach) on the two images of the same subject greatly increases the expert's The difficulty of identifying the location of the lesion and matching the two sets of images can easily lead to wrong matching of the lesion, which seriously affects the accuracy of the assessment of lesion progression

Abstract

The present application provides a medical image registration method, system and computer-readable medium, the method comprising the following steps: acquiring a first image and a second image; extracting rigid organs in the first image and the second image ; performing rigid registration on the rigid body organ according to the extraction result; and performing non-rigid registration on the target object according to the rigid registration result. This method greatly improves the matching accuracy of the target object by performing rigid registration and then non-rigid registration on medical images, thereby improving the accuracy of lesion progression evaluation during image reading; Registration further improves the matching accuracy of the target object, thereby further improving the accuracy of lesion progression assessment during film reading.

Description

technical field [0001] The present application mainly relates to the technical field of medical imaging, and in particular relates to a medical image registration method, system and computer readable medium. Background technique [0002] In the current film reading process, in the absence of intelligent comparison, the film reading experts need to visually observe the baseline (first shot) and visit (second shot) taken by the same subject at different times In order to compare the two sets of three-dimensional multi-slice images, the lesions can be aligned and matched. Because the difference between the subject's shooting posture (such as lying position and angle) and the subject's state (such as the difference between full and empty stomach in the stomach) on the two images of the same subject greatly increases the expert's The difficulty of identifying the location of the lesion and matching the two sets of images can easily lead to wrong matching of the lesion, which ser...
