Abstract:
1. A non-transitory computer readable medium embodying instructions executable by a processor to perform a method for non-rigid multi-modal registration, the method comprising: providing trained data corresponding to a prior registration; providing two or more images captured using different modalities; performing a non-rigid multi-modal registration of the two or more images, the non-rigid multi-modal registration comprising: determining a displacement field of the two or more images, wherein a first image of the two or more images is defined as a reference image and a subsequent image is defined as alignment image comprising, aligning the two or more images by adjusting the joint intensity distribution until an alignment of the two or more images corresponds to the joint intensity distribution substantially matching a learned joint intensity distribution of the trained data and a similarity measure between the two or more images satisfying a cost function, wherein the joint intensity distribution and the similarity measure are determined simultaneously during the alignment of the two or more images, and wherein the aligning of the two or more images comprises regularization of the displacement field between the two or more images and the trained data, wherein the method for non-rigid multi-modal registration is given by: where u is the displacement field,
