We propose the multi-volume super-resolution method to reconstruct isotropic voxels by merging several low resolution (LR) and non-isotropic volume data which is the scans of different orthogonal direction to obtain three orthogonal HR plane and LR slice-select data. This proposed super-resolution method is formulated as a maximum a posterior (MAP) estimation. In addition, we introduce laplace distribution as likelihood function in MAP estimation to consider nonconforming gaussian distribution such as magnetic nonuniformity and registration error. With visualized and quntitative evaluation, the experiments show that the proposed method can acheive much better HR data than the conventional SR method in simulation data and real mouse data with registration
error. |
