Title:
MULTI-MODAL IMAGE REGISTRATION METHOD AND DEVICE, ELECTRONIC APPARATUS, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/087659
Kind Code:
A1
Abstract:
The present application discloses a multi-modal image registration method. The multi-modal image registration method comprises: acquiring a first image in a source mode, and a second image in a target mode paired with the first image; correcting the intensity of the first image to acquire a first corrected image, such that an intensity distribution of the first corrected image matches that of the second image; acquiring, according to the first corrected image and the second image, a deformation field for registering the first corrected image to the target mode; and acquiring, according to the first image and the deformation field, a registered image for registering the first image to the target mode. The present application reduces the influence of an image intensity feature, avoids a decrease in precision caused by an excessively large distance between the same object in the first image to be corrected and an ideal registration result, and improves registration precision.
