Claim Text:
1. A non-transitory computer readable medium embodying instructions executable by a processor to perform a method for coregistration of multi-modal images, the method steps comprising: acquiring multi-modal volumetric image data, wherein the multi-modal volumetric image data includes volumetric image data of a first modality and volumetric image data of a second modality, wherein a same tissue captured in the image data of the first and second modalities has different geometries; defining a volume of interest in the multi-modal volumetric image data, wherein defining the volume of interest comprises: segmenting the volumetric image data of the first modality and incorporating priors of segmentation data of the first modality into a reconstruction of the volumetric image data of the second modality; and applying a registration to transform the second modality volumetric image data to align with the first modality volumetric image data according to a similarity measure through the 9-dimensional parameter space corresponding to the volume of interest, wherein an output of the registration comprises superimposed multi-modal volumetric image data wherein the geometries of the same tissue are aligned.
