Abstract: Provided are a magnetic resonance (MR) image processing apparatus and a method of reconstructing a MR image. The MR image processing apparatus includes a processor and a memory connected to the processor, wherein the processor is configured to acquire a partially sampled multi-coil k-space with respect to an object and obtain a reconstructed image of the object by reconstructing the partially sampled multi-coil k-space based on a pre-acquired first dictionary and a second dictionary acquired by using the first dictionary.

Abstract: A method for super resolution of an image imitating optical zoom implemented on a resource-constrained mobile device is includes inputting a first-resolution image. The method also includes assigning a super resolution factor from a predefined set of super resolution factors that indicate increasing the first resolution to obtain a second-resolution image. The super resolution factor indicates a trained intelligent system imitating the operation of the corresponding optical system among a plurality of intelligent systems trained for each super resolution factor of the predefined set of super resolution factors. The method further includes transforming the first-resolution image into the second-resolution image using said trained intelligent system.
