METHOD FOR ESTABLISHING NON-RIGID MULTI-MODAL MEDICAL IMAGE REGISTRATION MODEL AND APPLICATION THEREOF

A method for establishing a non-rigid multi-modal medical image registration model includes establishing a generative adversarial network GAN_dr; performing calculation with respect to structural representations of a reference image, a floating image, and an actual registered image in each sample in a medical dataset; using a calculation result to train GAN_dr; establishing a generative adversarial network GAN_ie; using the trained G_dr to generate the deformation recovered structural representations corresponding to each sample in the medical dataset; training GAN_ie; and after connecting the trained G_ie to G_dr, obtaining the registration model.
