MRI RESOLUTION ENHANCEMENT USING TOTAL VARIATION REGULARIZATION

We propose a novel method for resolution enhancement for volumetric images based on a variational-based reconstruction approach. The reconstruction problem is posed using a deconvolution model that seeks to minimize the total variation norm of the image. Additionally, we propose a new edge-preservin...
