摘要：
Medical imaging analysis systems are configured to perform automatic image registration algorithms that perform three-dimensional (3D), affine, and/or intensity-based co-registration of magnetic resonance imaging (MRI) data, such as multiparametric MRI (mpMRT) data, using mutual information (MI) as a similarity metric. An apparatus comprises a computer-readable storage medium storing a plurality of imaging series of magnetic resonance imaging (MRI) data for imaged tissue of a patient； and a processor coupled to the computer-readable storage medium. The processor is configured to receive the imaging series of MRI data； identify a volume of interest (VOI) of each image of the imaging series of MRI data； compute registration parameters for the VOIs through the maximization of mutual information of the corrected VOIs； and register the VOIs using the computed registration parameters.
